Revert "msm: acpuclock-krait: Confirm power-collapse before disabling CPU clocks"

Forward porting power-collapse check was band-aiding around the actual
root cause, which lay with the l2cpmr_iaddr value.

This reverts commit 8709dbcbdf9231e0d29897574dab74b3567245be.

Revert "msm: acpuclock-8960: fix indirect reg issues for elite"

This is the actual cause of periodic reboots for HTC 8960 devices.
Set l2cpmr_iaddr to 0x4501 and 0x5501 as is done for Qualcomm reference
boards.

This reverts commit 02787f256e326de19937cb5dd8403aeb52861832.
