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_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.
