Residency print is not working for 2 cases-
1. when the prev session stopped in the middle without
setting clk->prev freq to 0, in next session
the residency stats
for the same clk freq will not come as the start time will be
reset to 0 during next session open.
2. when last session close and clk rate not changed to 0
but, before that print residency stats come,
then in residency print the residency for
the last clk freq will not come.

Remove core check from all the functions in video driver.
ore check is present in most of the functions in video
driver which is not required.
Keep check only at root level functions and remove
the check from rest all of the functions.

- Instead of accumulating the residency stats for complete session,
the residency stats for previous instance of a particular clock
were overwritten by residency stats of next instance of that clock.
- Modified to the logic to accumulate the residency stats for
complete session.

In downstream, driver vote for VIDEO_CC_MVS0_CLK_SRC which
needs a multiplication factor of 3 to be applied to
required freq while on upstream we vote for branch clk
i.e. VIDEO_CC_MVS0_CLK hence this multiplication factor is
not needed.

Added changes to support generic power domain and opp table.
This is an alternative for downstream regulator framework.
power domain can be enabled using below dtsi entries.
power-domains =
<&videocc MVS0C_GDSC>,
<&videocc MVS0_GDSC>,
<&rpmhpd SM8450_MXC>,
<&rpmhpd SM8450_MMCX>
power-domain-names =
"iris-ctl", "vcodec", "mx", "mmcx";
Power domain handles willbe parsed at driver side using below api's.
- dev_pm_domain_attach_by_name()
- devm_pm_opp_attach_genpd()
devm_pm_opp_attach_genpd() provides consumer virtual device handles
and i.e linked to core->dev using device_link_add().
MXC, MMCX rails wilbe powered up by scaling desired rate using
dev_pm_opp_set_rate().

Use devm_reset_control_get_exclusive_released() instead of
devm_reset_control_get() to get the reset control of video_xo_reset
clock as it is shared reset clock between eva and video drivers.
Use reset_control_acquire() before assert and reset_control_release()
after de-assert video_xo_reset clock to avoid eva driver operating on
it in parallel.

handoff_regulator call.
[3] fw_power_control - moved to this state in case of IFPC.
[4] power_enable - will track core power_on/power_off status.
