This patch adds a new uvc attribute "uvc_num_request" to
set the number of uvc requests. And the maximum limit is
set to UVC_MAX_NUM_REQUESTS (8), the default value of
uvc_num_request is set to UVC_NUM_REQUESTS (4).

If usb gadget isochronous run in a high load and high bus latency
system, it may fail to start a transfer for isochronous endpoint,
and retry 5 times is not enough. This patch increases the retry
times to 50.

Isp transfer to ispp support quick or one frame mode
date support fbc or no fbc, set mode to node before
open ispp dev, default is one frame yuv422 fbc mode.
For the mode:
BIT(2): enable quick
BIT(1): enable yuv422
BIT(0): enable fbc
For example to quick yuv422 fbc mode:
echo 7 > /sys/module/video_rkispp/parameters/mode

Same as boot freq, prevent cpufreq drop to 816MHz which will make vdd_arm
drop to 0.725v.

This reverts commit 509d945c0ef72974cc18f0466cb4e6577a3c6c0e.
Use 79e05b456627("drm/rockchip: vop: Set mcu mode before setting output
mode and dither") as a better workaround.

When drive vop into mcu mode with mcu_hold enabled,
the following setting of output mode and dither will
not take effect until mcu_hold released.
So we can send mcu cmd at the default output P888 mode,
this give us a changce to avoid the cmd data to be changed
by dither module.

VOP wrongly treated MCU cmd as normal rgb data and pass it
to dither module when output mode is rgb565/rgb666, then
the cmd output from vop io is changed.
Here we convert the MCU cmd data from rgb565/rgb666 to rgb88,
so that we can get the original cmd data after dither module.

VOP MCU interface can't work right when dither enabled.
(1) the MCU cmd will be treated as rgb data then changed by
dither algorithm
(2) the dither algorithm works wrong in mcu mode
