[PATCH v2] drm/bridge: anx7625: Fix not correct get property counts

[Xin Ji]

The property length which returns from "of_get_property", it means array
bytes count if the property has prefix as "/bits/ 8". The driver should
call function "of_property_read_u8_array" to get correct array value.

Fixes: fd0310b6fe7d ("drm/bridge: anx7625: add MIPI DPI input feature")

V1 -> V2: Fix Sam comment, use of_property_read_u8_array to get array
value
