This reverts commit 0623a02a84. It leads to
panic during smmu faults because we do not have any recovery. Reverting
this will give the control to the client to dump if necessary.

Due to power-domain, if rotator driver is registered early,
probe might get deferred several times and get stuck
indefinitely. So, this change adds driver registration
after genpd init to handle such cases.

In 4.19 kernel, smmu driver will attach context bank soon
after device is probed. This change fixes display driver to
treat smmu context bank as pre attached.

pre-initialized from smmu.

1.Typecast to avoid distinct pointer type comparison
2.Keep DMA mask aligned with api definition.
3.Add Suffix for literals
4.Remove multfrac func to avoid uncompatible division.
5.64-bit division( operator "/") on 32-bit platforms is not supported.
Using platform independent API's here
