One way that mdp mixer2 gets writeback address is to get ion memory fd
from userspace, then mdp driver maps this fd in kernel. When mdp iommu
domain was not enabled, this maps to a physical address. Now after mdp
iommu domain is enabled, the map is changed to an iommu virtual addr.

Currently all HDMI timers are initialized in the driver's
probe function with a maximum possible expiration value. However,
the 32-bit jiffies value is initialized in the kernel so as to
wrap 5 minutes after boot. This results in the HPD timer being
fired 5 minutes after boot even though cable is not
connected. This change fixes this issue by not starting the HPD
timer during probe.

In the current implementation, the regulators pertaining to the
HDMI core are turned off/on as part of the configuration of the
HDP circuitry. As a result, the regulator that powers the HDMI
PLL is turned off before the HDMI clocks on the PLL are disabled.
This might lead to the PLL not getting locked when it is re-enabled.
This change turns on and off the regulators and clocks in proper
sequence.
