commit 21144298 (power: twl6035: add palmas PMIC support)
introduced twl6035_i2c_[read|write]_u8
Then, commit dd23e59d (omap5: pbias ldo9 turn on)
introduced palmas_[read|write]_u8 for precisely the same access
function. TWL6035 belongs to the palmas family, so instead of having
an twl6035 API, we could use an generic palmas API instead.

To stay consistent with the function naming of twl4030,6030 accessors,
we use palmas_i2c_[read|write]_u8

Since TPS659038/TWL6035/TWL6037 all belong to palmas family of TI PMICs,
rename twl6035_mmc1_poweron_ldo by a more generic palmas_mmc1_poweron_ldo
function.

Rename twl6035 to palmas to allow reuse across multiple current and
future platforms

As part of this change, change the CONFIG_TWL6035_POWER to
CONFIG_PALMAS_POWER and update usage of header file accordingly.

We handle i2c_write return code and complain in case of error. We propagate the
error, too, to allow better handling at the upper level in the future.

It can be optimised out by the compiler otherwise resulting
in obscure errors like a board not booting.

This has been documented in README since 2006 when these were
first fixed up for GCC 4.x.
