1. Define a new structure spi_ctrlr that allows platforms to define
callbacks for spi operations (claim bus, release bus, transfer).
2. Add a new member (pointer to spi_ctrlr structure) in spi_slave
structure which will be initialized by call to spi_setup_slave.
3. Define spi_claim_bus, spi_release_bus and spi_xfer in spi-generic.c
which will make appropriate calls to ctrlr functions.

For spi_setup_slave, instead of making the platform driver return a
pointer to spi_slave structure, pass in a structure pointer that can be
filled in by the driver as required. This removes the need for platform
drivers to maintain a slave structure in data/CAR section.

RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

The Kevin project has been too smooth and boring for our tastes in the
last last few weeks, so we've decided to stir the pot a little bit and
reshuffle all our PLL settings at the last minute. The new settings
match exactly what the Linux kernel expects on boot, so it doesn't need
to reinitialize anything and risk a glitch.
Naturally, changing PLL rates will affect child clocks, so this patch
changes vop_aclk (192MHz -> 200MHz, 400MHz in the kernel), pmu_pclk
(99MHz -> 96.57MHz) and i2c0_src (198MHz -> 338MHz, leading to an
effective I2C0 change 399193Hz -> 398584Hz).

rockchip_rk3399_pll_set_params() in the kernel and confirmed that GPLL,

patch to ignore frac divider when it's not used). Also confirmed that
/sys/kernel/debug/clk_summary now shows pclk_pmu_src 96571429 because
the kernel doesn't even bother to reinitialize the divisor.

To avoid garbage display in firmware on warm reset, we need

With a SPI clock above about 24MHz the APB cannot keep up when doing
individual byte transfers. Adjust the driver to use 16-bit reads when
it can, to remove this bottleneck.
Any transaction which involves writing bytes still uses 8-bit transfers,
to simplify the code. These are the transfers that are not time-critical
since they tend to be small. The case that really matters is reading from
SPI flash.
In general we can use 16-bit reads anytime we are transferring an even
number of bytes. If the code detects an odd number of bytes, it tries to
perform the operation in two steps: once in 16-bit mode with an even
number of bytes, and once in 8-bit mode for the final byte. This allow
us to use 16-bit reads even if asked to transfer (for example) 0xf423
bytes.
The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra
transfer when transferring ~>=64KB.

At higher SPI bus speeds the SPI RX value is not available in time for
sampling at the normal time. Add a delay to ensure that we read the
correct data.
The value of 40ns is chosen arbitrarily. In my testing I can use a sample
delay of 1 even at 24MHz. But since it is not necessary, I have left that
case alone. It kicks in at 25MHz and up.

Output GPIOs should never have a pull-up or pull-down resistor attached
since they're actively driven. Since some GPIOs get initialized with a
pull at power-on reset, we should explicitly overwrite that setting.
Most other platforms do this on gpio_output, but Rockchip hadn't yet.
Also, shuffle some code around to make things cleaner and allow for
easier code reuse.

The SPI driver is quite slow at reading data. For example, with a 24MHz
clock on gru it achieves a read speed of only 13.9Mbps.
We can correct this by reading the status registers once, then reading as
many bytes as are available before checking the status registers again. It
seems likely that a status register read requires synchronizing with the
SPI FIFO clock domain, which takes a while.
