In concurrency test, smmu map failure appears in a low possibility.
This is caused by virtual address conflict. Display driver calls
different smmu map APIs to do map with the same domain, while the
virtual address allocation happens separately, one in dmp-mapping.c,
and another one is in msm_gem_vam.c. This could not gurantee the
virtual addresses by different callers are different in the same
mmu domain, if they are the same, the virtual address will possibily
be mapped twice, hence conflict happens.
The change is to fix this:
1. Remove the map calling for early splash buffer from msm_smmu_map.
2. Introduce one new map API early_splash_map/unmap, dedicated for
memory mapping for early splash usercase.

Configure all I2C instances of SDM660, MSM8996 and MSM8998 for
SW bit banging based bus recovery mechanism. HW recovery may
not work as expected when HW samples the data line and finds
it low during particular clocking period of the recovery.
Use SW bit banging instead, where SW generate clock pulses and
sniff data line until data line is released by the slave.

The SD card specification allows cards to error out a SWITCH command
where the requested function in a group is not supported. The spec
provides for a set of capabilities which indicate which functions are
supported.
In the case of the power limit, requesting an unsupported power level
via the SWITCH command fails, resulting in the power level remaining at
the power-on default of 0.72W, even though the host and card may support
higher powers levels.
This has been seen with SanDisk 8GB cards, which support the default
0.72W and 1.44W (200mA and 400mA) in combination with an iMX6 host,
supporting up to 2.88W (800mA). This currently causes us to try to set
a power limit function value of '3' (2.88W) which the card errors out
on, and thereby causes the power level to remain at 0.72W rather than
the desired 1.44W.
Arrange to limit the selected current limit by the capabilities reported
by the card to avoid the SWITCH command failing. Select the highest
current limit that the host and card combination support.
