ENGR00181348-1 :sabresd pfuze support cpu internal LDO bypass
VDDCORE output directly from pfuze not internal anatop regulator,VDDCORE can
be adjust by pfuze regulator with deifferent cpu frequency, these patch should
be used with u-boot related patch, because LDO bypass is set on u-boot. u-boot
and kernel can be configured by CONFIG_MX6_INTER_LDO_BYPASS, by default it is
disabled, can be used on RevC. These code is put in arch/arm.
