msm: msm_bus: Add support for 64-bit bandwidth requests

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property  name, which
abides to the Device Tree convention.

msm: audio: qdsp6v2: Set end of frame flag to avoid aac multiseek issue

- During aac playback, multiple seek lead to target freeze.
- DSP starts decoding when internal buffer size maximum is
  reached, hence, if there are corrupted frames in that buffer,
  the entire set will not be decoded. This results in target freeze.
- Fix is to set the end of frame flag in the buffers that
  are sent to DSP for decoding.

msm: audio: qdsp6v2: Fix for jumping to next track when seeked to end

- During tunnel playback, when seek to end of the clip, and then
  seek back to other position, music player jumps to next track.
- When progress bar is dragged to end of the clip or beginning,
  this will invoke fsync function. fsync function waits for WRITE_DONE
  event from DSP. AUDIO_STOP or AUDIO_FLUSH should wake up fsync,
  but this wake up is not happening, as result driver issuing EOS
  cmd to DSP. Causing music player to jump to next track.
- Fix is to wake up the fsync during AUDIO_STOP and AUDIO_FLUSH.

msm_fb: display: replace msleep with wait4vsync

vsync is controlled by frame work which means vsync irq
off may happen at any instance. This patch use a reference
count to control vsync irq enable/disable so that
wait4vsync can replace msleep safely during suspend.

msm_fb: display: wait4vsync after timing generator is turned off

When continuous splash is enabled, timing generator is enabled at
bootloader, it then needs to be turned off at mdp4_dsi_video_on()
to switch displayed content from frame buffer. wait4vsync after
timing generator is turned off is necessary to make sure DMAP has
finished fetching splash logo from original splash buffer. Otherwise,
DMAP iommu page fault may happen.

msm_fb: display: wait4vsync before set suspend flag

Since wait4vsync checks suspend flag, wait4vsync needs to
be executed before suspend flag set to enforce wait happen.
Also, when timing generator is turned off, wait4vsync can
not be used anymore since the last vsync may have passed
before wait4vsync called. This patch fixed commit_comp
timeout cause fence timeout happen on hdmi plug and unplug
cases.

wfd on/off was handled by fb_on/fb_close which are called from video

driver has to register wfd for suspend to make sure proper panel
on/off happen.
