Updated build script
msm: clock: Remove the "auto_off" feature and add msm hotplug

The auto_off feature loops through all clocks in lateinit and disables
them if their reference count is 0, so long as the SKIP_AUTO_OFF flag
is not set. This has a significant functional overlap with the more
intelligent handoff feature.

In addition to detecting initial clock rates, handoff (like auto_off)
disables clocks in lateinit, but only if the clock was detected to be
on when the handoff op was called during msm_clock_init.

Currently, handoff does not support a skip flag like SKIP_AUTO_OFF,
which was used aggressively by proc_comm targets. Experimentally,
however, this does not seem to cause problems, possibly because
clocks are now being more selectively disabled.

Because there is no up-to-date documentation of the reasons why many
of these flags were set, the flags are just dropped by this patch
until their questionable utility can be re-evaluated.
