Commit 428826f535 ("fdt: add support for rng-seed") moves of_fdt_crc32
from early_init_dt_verify() to early_init_dt_scan() since
early_init_dt_scan_chosen() may modify fdt to erase rng-seed.
However, arm and some other arch won't call early_init_dt_scan(), they
call early_init_dt_verify() then early_init_dt_scan_nodes().
Restore of_fdt_crc32 to early_init_dt_verify() then update it in
early_init_dt_scan_chosen() if fdt if updated.

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

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.
