qcom: Deprecate QSIP_ON, a load switch enable
QSIP_ON is only valid on Trogdor rev-1. It controls the load switch
enable. The load switch is used for experiments but leaving it off
consumes power. On other Trogdor boards, QSIP_ON is just NC.
Since we no longer support Trogdor rev-1, deprecate the control in
the power sequence.
BRANCH=None
BUG=b:159999589
TEST=Build the Trogdor image.
