Some smd-rpm and voter rpm clocks are critical for system booting

So add support for handoff functionality for system critical rpm
clocks by using CLK_ENABLE_HAND_OFF flag.

MMC_PM_WAKE_SDIO_IRQ flag is used by platform driver(sdhci-msm
here) to determine if SDIO wakeup IRQ needs to be enabled
or not. If this flag is not removed in every mmc_resume_host,
then while suspend, platform driver will configure the sdio
wakeup IRQ even though wlan is disabled from UI.
This flag can be enabled by wlan driver before entring into suspend.
In this case since Wlan is not enable and thus not entering WoW mode,
pull up present on this SDIO GPIO line will pull the line high (which
otherwise is pulled low by wlan firmware in WoW mode and triggers
interrupt by pulling it high in WoW mode) which eventually will
trigger a false SDIO wakeup interrupt thus breaking the suspend
everytime.
Hence disable the flag everytime in mmc_sdio_resume and let
wlan driver enables it (-by sdio_set_host_pm_flags)
before entering into suspend if needed
for sdio wakeup part.

This patch enables the deferred resume support which would
prevent initialization of the card each time the system resumes.
With this change, the resume process would only be initiated if
a request is received.
Following scenario can occur:
1. device runtime suspended, system suspend is triggered
When resumed, the device would not be resumed until a
request is received.
2. device is runtime active, system suspend is triggered
When resumed, the device would be marked as BUS_NEEDS_RESUME
and actual resume would happen, when a request is received.
At this point, the device may also enter runtime-suspend or
system suspend may also occur. In both the cases, since the
device has not been resumed, it won't be suspended again.
However, the platform device would be runtime suspended
and resumed as before.
It can so happen that the card is removed even before a
request is received. In this case the device would be
resumed and card would be removed from core layer and
upper layers would be notified.
In case of SDIO cards, this change would not have any effect
since manual resume would be enabled for devices supporting
a block read/write commands.

During suspend/resume, the driver writes to AUTOBKOPS_EN bit in
EXT_CSD register of eMMC which is R/W/E. Even after power off
R/W/E bit will retain it's value, as it will be stored in NAND
flash. Multiple writes can wear out the specific NAND block which
store the system data(AUTO BKOPS bit in this case). So to avoid
this, enabling/disabling of autobkops has been removed from
suspend and resume. The background operations, if any, will stop
when sleep command is sent during suspend process.

Commit dd7ad27eb3de6b088b6525b066c40f5a29ac4c60 ("msm: mdss: fix
race condition between iommu attach and sending DCS cmds") protected
the iommu attach/detach to fix possible race condition between the
display thread and DCS cmd sending from ESD or some other thread with
iommu_lock. But this still leaves possibility of race condition based
on iommu_attached status flag.
-> Display thread finishes the attach and releases the iommu lock
-> DCS cmd thread gets the iommu lock and checks iommu_attached
status before display thread could change it.
Protect the iommu_attached status variable along with iommu
attach/detach to avoid such cases.

WB timeouts are seen when WB is connected after 4k HDMI
use case. This was seen when WB is using the same mixer
which was earlier used by HDMI, with 3D Mux enabled.
Since 3D Mux registers are double buffered, the best way
to clear control operations is to re-use the control path.
Hence allowing WB to choose the first available control
path.

considers DSI0 and DSI1 as separate displays even if
split display is enabled. So the number of displays
are calculated as 2 whereas the driver considers this
as a single display. This causes MDP clocks to remain
ON. This change corrects number of displays calculated
by checking for split display.
