twl6035: rename to palmas
TPS659038/TWL6035/TWL6037 all belong to palmas family of TI PMICs
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.
