drm/rockchip: ebc_dev: release version v8.00

adjust and improve fast mode:

bw_enable_repair 0: disable fast mode, no ghost remove
bw_enable_repair 1: ghost remove level 1
bw_enable_repair 2: ghost remove level 2
.
.
.
bw_enable_repair 7: ghost remove level max
bw_balance_ctl 0: disable balance ctl under fast mode, default 0, can
update by userspace ioctl
bw_balance_ctl 1: enable balance ctl, limited pixel imbalance
