msm: clock: add handy HTC clock debugging function

Change-Id: Ib140faffdba0abd880befa322bd2558818ccda49
msm: sps: adapt to clock API change

With the change in clock driver, clk_get() can return -EPROBE_DEFER even
when the clock is actually present in HW. Thus, we need to return
-EPROBE_DEFER in SPS driver probe function if clk_get() fails.

msm: sps: improve BAM inactivity timer function

1> Add the support for BAM global inactivity timer which is a new feature
in B family.
2> There is an update that changes the time unit of the inactivity timer
counter from 0.1ms to 0.125ms. Thus, we adjust the parameter in SW driver
for this update.
3> Inactivity timer timeout interrupt will become a new type of BAM global
interrupts, and it is a normal interrupt different from other BAM global
error interrupts. Thus, change the log level for callback message from INFO
to DEBUG.
4> Change timer result argument of inactivity timer API to an optional one
for client drivers.

msm: sps: enable BAM DMA client to control BAM DMA clock

For power saving reason, SPS driver will turn off the clock of
BAM DMA after the initial configuration. A new API is provided
to BAM DMA clients to vote for or relinquish BAM DMA clock when
they start/stop using BAM DMA.

msm: sps: turn off BAM DMA clock after initial config

For power saving, SPS driver will turn off BAM DMA clock after the
initial configuration of BAM DMA. The clients of BAM DMA will vote
for the clock when BAM DMA is used.
