msm_fb: hdmi: change HDMI_PHY_REG1 based on foundry.

Set value of HDMI_PHY_REG1[2:0] for output voltage swing control,
to prevent fallout for Vlow for GF foundry MSM's.

Revert "msm_fb: display: remove wait4vsync during dtv off"

msm_fb: display: Add compulsory wait after DTV's TG is disabled.

When DTV timing generator is disabled during dtv_off, a wait for
at least a frame period is required. This is done by waiting on
vsync. In some scenarios, vsync interrupt is received such that, no
wait really happens which results in MDP hangs.
Add wait for 20ms after TG is disabled, to ensure wait for at least
a frame period. Also, print timeout error in case wait for vsync
times out.

msm: sps: update clocks for 8974 in SPS driver

Two changes for clocks:
1> Vote for dfab_clk which is the peripheral NOC on 8974;
2> Do not vote for mem_clk since it does not exist on 8974.

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_fb: HDMI: Fix for high HDMI sleep current

In certain cases, the HPD circuitry is not switched off when the
device goes to suspend state, resulting in high sleep current on
the HDMI power rail. This patch ensures that the HPD circuitry is
always turned off during suspend operation by removing an
unnecessary condition check.

Revert "msm: move printk out of spin lock low_water_lock"

This reverts commit 749c4210f338496abf2e16ef51308ff756b34f7b.

This patch is a hack intended to solve a particular instance of a more
generic problem. The cause of the spindump timeout has been fixed with
the commit f37a3dc536e4ecd72961a2d9c77f5587c5c55d8f. Furthermore this
change also introduces a race condition since the printk is actually
intended to be protected with the spinlock.
