RTC drivers now select RTC, so that code which depends on them
can implement fallback behavior for systems that lack the
hardware or driver.

These files were trying to document the parameters, but didn't have
the syntax quite right. Change the comments from @varname to
@param varname as required by doxygen.

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

This imports TPS65090 PMIC from u-boot and adds/updates Makefiles
and Kconfig files. The follow-up patch will re-factor the code.
