now.

Currently, the driver defers if it doesn't find a drm_panel. This forces
us to have a drm_panel, if not, the driver isn't usable.

Make the lcdc encoder initialization independent of the availability of
the drm panel. We only check if there is a panel node specified in DT. If
it isn't, then we don't initialize the encoder at all. The panel node is
passed to the lcdc encoder and lvds connector drivers.

The connector driver takes the responsibility to retrieve the drm_panel
from the panel node, and update the status on whether the panel is
connected or not. This makes the panel usable even if the drm_panel
driver is inserted as a module later on.

modeset_init() for mdp4 isn't very flexible. That makes it hard to add
more interfaces.

Split out the encoder/connector creation code in modeset_init into a
separate function. This is similar to what's done in modeset_init for
mdp5.

Remove CONFIG_OF checks in adreno_device.c. The downstream bus scaling
stuff is included only when CONFIG_OF is not set. So, remove that too.

We don't intend to use downstream non-DT kernels anymore, so remove

Support for non-DT kernels was mainly to use v3.4 downstream kernels.
This is no longer a priority now as we have reasonable support upstream.

MDP5 has line count and frame count registers for each interface. Enable
these counters and use them to implement the get_vblank_timestamp drm
driver op.

The line counter starts with the value 1 at the beginning of the VSYNC
pulse and ends with value VTOTAL at the end of VFP. This value is used
to determine whether we're in blanking period or not, and an adjusted
value of this counter is used to get vpos as expected by
get_scanout_position. Since there is no way to calculate hpos, we always
set it to 0.
