ENGR00276023-2: board: freescale: mx6q: add ldo bypass interface on boards
There are three types of board for ldo bypass feature:
1.The board support ldo bypass feature, because of pmic exist. Then implement
the full function in the board file. such as mx6qsabresd/mx6slevk
2.The board can't support ldo bypass feature, although pmic still be here. For
example: WDOG reset pin and RESET key are not connected with PWRON of pfuze on
Sabreauto board, hence at worst case chip can't boot again(reboot failed while
system run on 400Mhz, because ROM boot on 800Mhz and the external pmic voltage
still be kept @400Mhz). On these board we only implement 1.2G check and
increase VDDARM/VDDSOC automatically. Force to ldo-enable mode always.
3.There is no PMIC on the board, hence LDO bypass feature cannot be supported.
In this case, ldo_mode_set() is an empty function.
