The current interface of intel_gvt_register_hypervisor() expects a
non-const pointer to struct intel_gvt_mpt, even though the mediator
never modifies (or should modifiy) the content of this struct.
Change the function signature and relevant struct members to const to
properly express the API's intent and allow instances of intel_gvt_mpt
to be allocated as const.
While I was here, I also made KVM's instance of this struct const to
reduce the number of writable function pointers in the kernel.

Add the clocks entries used in the video clock path, the clock path is
doubled to permit having different synchronized clocks for different parts
of the video pipeline.
The AXG only has a single ENCL CTS clock and even if VCLK exist along
VCLK2, only VCLK2 is used since it clocks the MIPI DSI IP directly.
All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are
flagged with CLK_IGNORE_UNUSED since they are currently directly handled by
the Meson DRM Driver. Once the DRM Driver is fully migrated to using the
Common Clock Framework to handle the video clock tree, the
CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED will be dropped.

Remove tegra20-devfreq in order to replace it with a EMC_STAT based
devfreq driver. Previously we were going to use MC_STAT based
tegra20-devfreq driver because EMC_STAT wasn't working properly, but
now that problem is resolved. This resolves complications imposed by
the removed driver since it was depending on both EMC and MC drivers
simultaneously.

In omap4_keypad_probe, the patch fix several bugs.
1) pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak.
2) In err_unmap, forget to disable runtime of device,
pm_runtime_enable will increase power disable depth. Thus a
pairing decrement is needed on the error handling path to keep
it balanced.
3) In err_pm_disable, it will call pm_runtime_put_sync twice not
one time.
To fix this we factor out code reading revision and disabling touchpad, and
drop PM reference once we are done talking to the device.

Commit 22337b9102 ("arm64: dts: qcom: sc7180: Changed polling mode
in Thermal-zones node") sets both 'polling-delay' and
'polling-delay-passive' to zero with the rationale that TSENS interrupts
are enabled. A TSENS interrupt fires when the temperature of a thermal
zone reaches a trip point, which makes regular polling below the passive
trip point temperature unnecessary. However the situation is different
when passive cooling is active, regular polling is still needed to
trigger a periodic evaluation of the thermal zone by the thermal governor.
Change 'polling-delay-passive' back to the original value of 250 ms.
Commit 2315ae70af ("arm64: dts: qcom: sc7180: Add gpu cooling
support") recently changed the value for the GPU thermal zones from
zero to 100 ms, also set it to 250 ms for uniformity. If some zones
really need different values these can be changed in dedicated patches.
