The open method for the debug fops are supposed to extract
the appropriate register base for the corresponding
hardware blocks, which are later used for the register
read and writes for the associated hardware block. But
the current open method being used points to some random
register base which can lead to fatal issues when performed
reads and writes to registers. Hence implemented a new
open method to extract the appropriate register base of the
various mdp hardware blocks. This patch also fixes
the valid sub range check against the corresponding
hardware blocks instead of checking across all the hardware
blocks.

Add runtime_pm ops support in drm driver instead
of direct sde_power_resource_enable/disable call.
It allows drm driver to use runtime pm refcount logic
to track the resources instead of custom implementation.
The change also removes the NRT_CLIENT support from
sde_power_handle code to simplify it further.
