OMAP4460: TWL: disable PD on VCORE1 shutdown
When the PREQ goes low, both VCORE1(VDD_CORE) and VDDD_MPU
start transitioning to 0 volt but VCORE1 discharge is faster
than VDD_MPU discharge. This causes reliability concern from
OMAP's perspective. So, we disable pulldown on VCORE1 to
slow down VDD_CORE discharge to make it comparable to VDD_MPU.
The Pulldown does not impact DVFS transition, and actual
OFF timing is not changed as well.
