When trying to find the parent i2c bus of a given device, ensure that
the bus link doesn't point to itself, else we'll get stuck in an
infinite loop.

This patch adds the I2C equivalent of an SMBus quick write to an I2C
device, which is used by some I2C drivers as a way to probe the
existence (or absence) of a certain device on the bus, based on
whether or not a 0-byte write to an I2C address is ACKed or NACKed.
i2c_dev_detect() is implemented using the existing i2c bus ops transfer()
function, so no further work is needed for existing controller drivers
to utilize this functionality.

device: Correct code style
Revise the following aspects to follow coreboot's coding style:
- Drop braces for single-statement condition.
- Remove unnecessary newlines.

Revise the following aspects to follow coreboot's coding style:
- Drop braces for single-statement condition and loop bodies.
- Use `__func__` to print the current function's name.
- Reflow pointer dereferences to fit in a single line.
- Adjust the `*` position in pointer variable declarations.
- Drop unnecessary `else` statements.

Stefan thinks they don't add value.
Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)
The exceptions are for:
- crossgcc (patch file)
- gcov (imported from gcc)
- elf.h (imported from GNU's libc)
- nvramtool (more complicated header)

i2c_dev_read_at16() sends a 16-bit offset to the I2C chip (for larger
EEPROM parts), then reads bytes up to a given length into a buffer.

If one wants to implement both i2c_bus.h and i2c_simple.h APIs
the compilation unit needs to be guarded or coordinated carefully
with different compilation units. Instead, name the i2c_bus
functions with _dev such that it indicates that they operate on
struct device. One other change to allow i2c_bus.h to be built in
non-ramstage environments is to ensure DEVTREE_CONST is used for
the dev field in struct bus.

Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.
To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.
We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().
