Subject: [PATCH] regulator: Use BUCK_FPWM_[MASK|SHIFT] macros to replace
 buck_pmap table

Below is the buck_pmap mapping table:

BUCK1:  mask = 1 << 0,  shift = 0
BUCK2:  mask = 1 << 1,  shift = 1
BUCK3:  mask = 1 << 2,  shift = 2
BUCK4:  mask = 1 << 3,  shift = 3

The mask and shift can be easily calculated by:
        mask = 1 << BUCK_ID
        shift = BUCK_ID

This patch defines BUCK_FPWM_MASK and BUCK_FPWM_SHIFT macros to replace
buck_pmap mapping table.
