[why]
HDCP 1.4 failed on SL8800 SW w/a test driver use.

[how]
Slow down the HW i2c speed when used by HW i2c.
This request: each acquired_i2c_engine setup the i2c speed needed
and sets the I2c engine for HDCP use at release_engine.

This covers SW using HW i2c engine and HDCP using HW i2c engine.
for dmcu using HW i2c engine, needs add similar logic in dmcu fw.

[Why]
During driver unload, it is expected that p-state switching is supported.
If it's not supported, PMFW will hang due to a forced p-state switch. Even
if the current timing does not support p-state normally, we still want to
force allow because the worst that can happen is underflow. This will
match Navi10 behaviour.

[How]
 - new hubbub func to control the force pstate register
 - force allow when releasing display ownership
   - registers are inaccessible after due to m_cgs.hwNotAvailable
 - explicitly disable force signal during hw_init
   - if driver is disabled and re-enabled, register not cleared otherwise

Also, remove DCN3 part of dcn10_init_hw, we will not be going back to it.

[Why]
with eDP + DP, each display use one pipe. after DP unplugged, eDP switch
from one pipe to two pipes -- pipe split.  dpp1_cm_set_regamma_pwl will
be executed too. The duration from switch single pipe to dual pipes is a
little long which could let eDP enter PSR mode. upon two pipes for eDP
are setup, eDP PHY is disabled. front pipe is not really running to
fetch data from frame buffer. i.e., dchubp is not in normal working
status. execution of hubbub1_wm_change_req_wa may cause p-state warning.

[How]
disable eDP PSR before dc_commit_state. psr is disabled when execute
hubbub1_wm_change_req_wa.

hardware on boot will ensure SW state is accurate.

[HOW]
Set a timer callback on boot for 10 seconds. If set mode is not called
within that time, power down hardware. Otherwise, do not power down.

[why]
DP link layer CTS specs updated to change the test parameters in test
4.2.1.1.
Before it requires source to delay 400us on aux no reply.
With the specs updates Errata5, it requires source to delay 3.2ms
(based on LTTPR aux timeout)
This causes our test to fail after updating with the latest test
equipment firmware.

[how]
the change is to allow LTTPR 3.2ms aux timeout delay by default.
And set back to 400us if LTTPR feature is not enabled.
We will set 3.2ms and always enable LTTPR non transparent mode
if LTTPR feature is enabled and LTTPR is present.
