while they had no users. Now that the driver supports clocks

The dmc driver supports changing min_freq and max_freq according to
system status and vop bandwidth at present. But even if user changes
governor to userspace, the ddr frequency may also change constantly.
This patch adds a new dmc_ondemand governor which doesn't chang min_freq
and max_freq, it can also support changing ddr frequecy based on usage,
system status and vop bandwidth. So users can set their own frequency by
the userspace governor.

There is a frequency map table between vop bandwidth and dmc, when vop
bandwidth is changed, the dmc frequency will also be changed to specified
frequency.
If new request frequency is greater than old request frequency, update dmc
target frequency immediately. If new request frequency is less than old
request frequency, only update min_freq and max_freq.

The userspace may do an invalid mtp_open operation, e.g. the
usb function is configured to ADB only mode, but the userspace
may still call mtp_open operation because of error state machine
in the userspace. In this case, if the userspace try to set usb
function as ADB + MTP next time, it will call mtp_open again
and finally fail because that mtp_lock is busy, so the fp->
private_data is uninitiated. And this will cause cdev to be
NULL pointer in mtp_read and mtp_write.

According DWC-OTG databook, after the CSftRst bit is cleared,
the application must wait at least 3 PHY clocks before doing
any access to the PHY domain. And longer delay is required for
some rockchip soc based platforms. But current delay time is
not long enough for rk312x and it will result in repeately
trigger of ID change interrupt of dwc2 controller. This patch
increase delay time from 50 millisecond to 80 millisecond to
make sure that dwc2 controller and PHY is synchronized.

In both legacy and mq path, req count of plug list is computed
before allocating request, so the number can be stale when falling
back to slept allocation, also the new introduced wbt can sleep
too.
This patch deals with the case by checking if plug list becomes
empty, and fixes the KASAN report of 'BUG: KASAN: stack-out-of-bounds'
which is introduced by Shaohua's patches of dispatching big request.

Currently block plug holds up to 16 non-mergeable requests. This makes
sense if the request size is small, eg, reduce lock contention. But if
request size is big enough, we don't need to worry about lock
contention. Holding such request makes no sense and it lows the disk
utilization.
In practice, this improves 10% throughput for my raid5 sequential write
workload.
The size (128k) is arbitrary right now, but it makes sure lock
contention is small. This probably could be more intelligent, eg, check
average request size holded. Since this is mainly for sequential IO,
probably not worthy.
V2: check the last request instead of the first request, so as long as
there is one big size request we flush the plug.

This patch adds helper functions for YCBCR 420 handling.
These functions do:
- check if a given video mode is YCBCR 420 only mode.
- check if a given video mode is YCBCR 420 also mode.
V2: Added YCBCR functions as helpers in DRM layer, instead of
keeping it in I915 layer.
V3: Added handling for YCBCR-420 only modes too.
V4: EXPORT_SYMBOL(drm_find_hdmi_output_type)
V5: Addressed review comments from Danvet:
- %s/drm_find_hdmi_output_type/drm_display_info_hdmi_output_type
- %s/drm_can_support_ycbcr_output/drm_display_supports_ycbcr_output
- %s/drm_can_support_this_ycbcr_output/
drm_display_supports_this_ycbcr_output
- pass drm_display_info instead of drm_connector for consistency
- For drm_get_highest_quality_ycbcr_supported doc, move the variable
description above, and then the function description.
V6: Add only YCBCR420 helpers (Ville)
V7: Addressed review comments from Ville
- Remove cea_vic_valid() check.
- Fix indentation.
- Make input parameters to helpers, const.
