We don't intend to use downstream non-DT kernels anymore, so remove
CONFIG_OF checks.
Update the TODO comment so that we don't forget about max_clk setting
for non APQ8064 chips having MDP4.

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.
Remove CONFIG_OF from the top level msm_drv.c file. While we're at it,
clean up the data matching process using of_device_get_match_data.

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.

for_each_matching_node() performs an of_node_get() on each iteration, so
a break out of the loop requires an of_node_put().
A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>

local idexpression n;

Checking for sor->aux in eDP specific code is unnecessary because eDP
inherently requires a valid AUX channel.

Instead of getting a pointer to the driver-specific wrapper of AUX
