Use the same function name as in soc/intel for this functionality. This
also brings the function name more in line with the extended version of
this function gpio_configure_pads_with_override which additionally
supports passing a GPIO override configuration.
This might cause some pain for out-of-tree boards, but at some point
this should be made more consistent, so I don't see a too strong reason
not to do this.

The UARTs in the Picasso SoC are memory mapped, but there is also some
hardware support that isn't used by any board to make the UARTs behave
like the ones found on legacy x86 machines from the 90s.
In the MMIO mode the MMIO address of the UART controller is passed to
the OS via ACPI. The OS expects the base clock of the UART controller to
be 48MHz (see the cz_uart_desc struct in drivers/acpi/acpi_apd.c and
drivers/tty/serial/8250/8250_dw.c in the Linux kernel) in this case. It
is also possible to enable additional decodes from four 8 byte legacy
I/O locations used for serial ports to the different UART controllers,
which doesn't disable the MMIO access though. The legacy I/O-mapped
serial ports are usually expected to have a base clock of 16*115200Hz
which the hardware can also provide to the UART's baud rate generator.
So there are two possible valid configurations to use the UARTs; either
MMIO access in combination with a 48MHz base clock or the legacy I/O
decode with a ~1.8MHz base clock.
The existing code unconditionally generates ACPI objects for all enabled
UARTs, so those shouldn't be put into legacy mode and switching the base
clock to ~1.8MHz was only done in the case that the UART was used as
coreboot console UART which still used the MMIO access, but the lower
base clock. Since no board even selects this option and it's rather
invasive to properly implement this feature, just drop the corresponding
broken code.
TEST=SoC UART console still works on Mandolin.

This change includes uart.c in bootblock, romstage, ramstage and
verstage unconditionally because this file is handling more than just
the UART console configuration. This allows boards to take advantage
of picasso_uart_mmio_ops even if PICASSO_UART is not selected.

PICASSO_UART is unset, so add an #if around those functions.

The legacy UARTs are supposed to default to off according to the
documentation (PPR for AMD Family 17h Model 18h). But legacy UART Range_0
is enabled after reset. The PSP might be enabling it or the documentation
might be wrong.
Having it enabled causes problems though. We have ACPI nodes defining
MMIO UARTs, and the kernel also probes for legacy UARTs. This results in
two drivers accessing the same device, one via MMIO and one via IO. I
suspect this was the cause of the garbage serial output.
Before the change you would see the following in the console:
[ 0.741108] serial8250: ttyS3 at I/O 0x2e8 (irq = 3, base_baud = 115200) is a 16550A
After this change, we no longer see it.

2. scan_bus: Uses scan_static_bus to scan devices added under the UART

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

So that everyone can see what's being updated from stoney, we're
starting with a direct copy of the stoney directory. There are
arguments both for and against doing it this way, but I believe
This the most transparent way. We've moved much of the duplicated
stoney code into the soc/amd/common directory and will continue
that work as it becomes obvious that we have unchanged code between
the SOCs.
Makefile.inc has been renamed as makefile.inc so that it won't
build in jenkins until the directory is updated.
Other than that change, this is an exact copy of the stoneyridge
SOC directory which will be updated in the follow-on commits in
