mako: Remove 5V FRC gpio external regulator

msm: 8064-regulator: Remove 5V FRC gpio external regulator
Jay Chokshi <jchokshi@codeaurora.org>

On MPQ-8064, 5V FRC regulator coordinates with FRC
reset signal in certain timing sequence, which is
controlled by FRC driver powerup sequence. The FRC driver
is implemented in Userspace.

Since kernel claims the same GPIO line to control as a
gpio voltage regulator, FRC Userspace driver fails to
handle it. Relinquish the control of the gpio line
as there are no kernel clients of the gpio anyways.
