Revert "msm: msm_bus: Add support for 64-bit bandwidth requests"

This reverts commit f0353efc6b4f5760515bdb577c944720ae113201.
msm_rotator: comment non-existing code
msm_fb: fixup jb_mr1_chocolate merge
msm: event_timer: Support to add event timers.

Add support to allow drivers to specify future events
that need to be treated as hard deadlines. Upon event timer
expiry the driver will be notified by callback function
that the driver provides.
The pm code can query the earliest event and modify
the event timer accounting for the back off based on the
latency of the low power mode being entered.
