Subject: drm/rockchip: fix integer type used for storing dp data rate
Git-commit: c3b040b5c58f9a2de8f672f9e7cb1a8d411b9f23
Patch-mainline: v5.5-rc7
References: bsc#1152472
commit 2589c4025f13 ("drm/rockchip: Avoid drm_dp_link helpers") changes
the type of variables used to store the display port data rate and
number of lanes to u8. However u8 is not sufficient to store the link
data rate of the display port.
This commit reverts the type of data rate to unsigned int.
