The omap24xx I2C driver uses its own CONFIG namespace for common I2C
variables. Rather than convert more of them to Kconfig, rename these to
the common I2C ones and remove the entirely unused functionality. As
part of this, we make the am335x_shc platforms consistent with their
intended speed values.

First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig. Next, as you cannot
have SYS_I2C_LEGACY and DM_I2C at the same time, introduce
CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only
in SPL. Finally, for some PowerPC cases we also need
CONFIG_TPL_SYS_I2C_LEGACY support. Convert all of the existing users to
one or more symbols.

To avoid confusion about the order of the GPIOs, the i2c-gpio binding
was updated to use a separate property for each GPIO instead of an
array. However, the driver only supports the old binding. Add support
for the new binding as well, so the driver continues to work as device
trees are updated.

At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason
CONFIG_I2C is not strictly necessary is that:
a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible
i2c stacks
b) In U-Boot proper, we always build drivers/i2c/ regardless of the
options
Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to
SPL/TPL, so we can (in a future commit) simplify the Makefile rules.
Enable it by default, since as above, we have separate options
(SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled.
Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and
make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.

It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and
CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less
than a year away.
Also we want to have a CONFIG_I2C for U-Boot proper just like we have
CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules.
Rename this symbol so it is clear it is going away.

At present if U-Boot proper uses driver model for I2C, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.
This patch introduces a separate Kconfig symbols for enabling DM_I2C and
DM_I2C_GPIO support in SPL.
This will also help to get away from dirty workarounds to
achieve non-DM I2C support for SPL, which is currently used in some
board header files like:
ifdef CONFIG_SPL_BUILD
undef CONFIG_DM_I2C
endif

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro
