Use #if IS_ENABLED() instead of #ifdef for configurations as vendor module
guidelines.
Use #if IS_ENABLED(CONFIG_XXX) instead of #ifdef CONFIG_XXX to ensure that
the code inside the #if block continues to compile if the config changes
to a tristate config in the future.
The differences are as follows:
1.#if IS_ENABLED(CONFIG_XXX) evaluates to true when CONFIG_XXX is set to
module (=m) or built-in (=y).
2.#ifdef CONFIG_XXX evaluates to true when CONFIG_XXX is set to
built-in(=y) , but doesn't when CONFIG_XXX is set to module(=m).
Use this only when you're certain you want to do the same thing
when the config is set to module or is disabled.

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.

This change enables and exports configs to support SDE
offline rotator in GKI. It also removes unused ioctls
for rotator compilation with GKI config.

Added code for dummy probe defined under
CONFIG_SDE_ROTATOR_INIT_ONLY to address cases where
rotator device node is defined but driver needs to be
disabled. This is stop gap arrangement until v4l2
configs are available in GKI.

Added uapi and device_caps changes to enable rotator
compilation and address video device registration failure.
Device_caps field is must for video device registration
unless it is sub device.

Few v4l2_ioctl_ops are deprecated on kernel upgrade. Made
changes to use the new simulated ops. Addressed compilation

Make msm_drm into single module and all child driver
registers and unregisters are handled from parent's
register and unregister respectively.

Doing late initialization of rotator module since it depends
upon providers which are initialized during msm bind time.
Hence, calling rotator module init only after msm module
init is complete.
