iommu/core: pass a user-provided token to fault handlers

Sometimes a single IOMMU user may have to deal with several
different IOMMU devices (e.g. remoteproc).

When an IOMMU fault happens, such users have to regain their
context in order to deal with the fault.

Users can't use the private fields of neither the iommu_domain nor
the IOMMU device, because those are already used by the IOMMU core
and low level driver (respectively).

This patch just simply allows users to pass a private token (most
notably their own context pointer) to iommu_set_fault_handler(),
and then makes sure it is provided back to the users whenever
an IOMMU fault happens.

The patch also adopts remoteproc to the new fault handling
interface, but the real functionality using this (recovery of
remote processors) will only be added later in a subsequent patch
set.

msm_fb: display: balance bus bandwidth on mdp axi port0 and port1

mdp read and write clients are connected on both mdp port0 and port1,
however, the bus bandwidth request is made on only port0. This change
divides mdp bw requests to port0 and port1 based on pipe connections
to mdp ports.
ab - no scaling factor - port0 and port1 split
ib - scaling factor - port 0 and port1 split

msm_fb: display: add scaling factor for mdp ab

system profiling found that mdp downscaling needs larger bandwidth
that is related to mdp ab request, so adding scaling factor to mdp ab
calculation reduces the chance of underruns.

ab - scaling factors - port0 and port1 split
ib - 1.5 x ab - no split and same on both ports

msm_fb: display: keep a minimum mdp ib bandwidth request

The calculated ab and ib bandwidth requests are very small which cause
underruns if mdp composites only very small layers. For these use
cases keeping a minimum ib request based on the baselayer size can
prevent underruns and no power impact is observed.

msm_fb: display: Program source address registers correctly

Scale filter FIR uses the adjacent pixels as part of the
processing. Source address registers should be program such that
they point to the first valid pixel so that non-ROI pixels are
ignored. This is done by making source x,y offsets to zero and
adding the computed offset to source address.

msm_fb: display: fix the hang issue caused by solidfill pipe

When mdp pipe solidfill mode is disabled, the staled pipe info is used
to update mdp pipe regs. This caused mdp hang. Since
mdp4_overlay_rgb_setup function already resets solidfill mode, this
patch removes any pipe register updates that are related to disabling
solidfill mode.

msm_fb: hdmi: Remove supported resolution check

The change will remove the supported resolution check while turning
on the HDMI. The supported resolution is updated on parsing EDID for
VIC and matching it with default mode in HDMI. This may fail in case
the default video mode is not available in EDID of TV resulting in
HDMI turn on failure.

Also, this check is not needed because we now have the HDMI display
pipe line check which will make sure we do not turn on HDMI if it
is not supposed to be turned ON.

msm: mdp: Fix reserved field usage

An earlier commit(ec5b2f)increased the number of reserved fields
in the kernel standard fb.h header changing the struct size.
This caused issues with userland applications using the corresponding
bionic header. This patch revert the earlier increas in size
and makes corresponding adjustments to the reserved field usage.
A follow up patch will remove usage of reserved fields entirely.
