[U-Boot] [PATCH] power: twl6035: cleanup register access API

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 palmas API,
we could use twl6035 API instead (which is used elsewhere
as well).

Account for the parameter change while doing the change and
remove palmas register accessors.
