regulator: twl-regulator - fix twlreg_set_mode

The Singular Message is 16 bits:
        DEV_GRP[15:13] MT[12]  RES_ID[11:4]  RES_STATE[3:0]

Current implementation return immedially after sucessfuly write MSB part.
To properly set mode, we need to write the complete message ( MSB and LSB ).

In twl.h, now we have defines for PM Master module register offsets,
use it instead of hard coded 0x15/0x16.

Use "message & 0xff" to ensure we send correct value for LSB.
