This change fixes dcn10 front end reset sequence. Previously we
would reset front end during flip which led to issues
in certain MPO and 4k/5k scenarios. We would also never properly
power gate our front end.

always take update lock instead of using HW built in update
lock trigger with write to primary_addr_lo.
we will be a little more inefficient with the extra registers
write to lock, but this simplify code and make it always correct.
Will revisit locking optimization once update sequence mature

1. remove the sleep mechanism while set_blank true from
the timing generator.
Since Hw sequencer is the one that manages the flow
he will be responsible for wait for blanck in a critical places.

The dc_gamma in dc_surface will be programmed to the input
LUT if provided. If dc_gamma is not provided in dc_surface
regamma may be used to emulate gamma.
Some refactor and cleanup included as well.

Refactor part 3 - Moving output transfer function from surface to stream
Split HWSS to program degamma and regamma separately.
Degamma should be dependent on input transfer function.
And Regamma should depend on the desired output transfer function.

Refactor part 1 of degamma/regamma programming.
End goal is to have source and output transfer function in
which dc can use to decide how to program the degamma
and regamma HW.
Gamma will be explicitly applied through
dc_update_surfaces_for_target.
Color module should build the logical curve with all
adjustments applied and pass enough information
for dc to program HW PWL.

- Introduce GRPH_UPDATE_LOCK around programming surface flip.
- Remove the now unused graphic surface lock.
- Add macros to get and set four registers
- both immediate and H Retrace should not be enabled at the same time
