LF-95-5 drm/imx: imx-ldb: Correct control register offset for i.MX8QM/QXP LDB

The i.MX8QM/QXP LDB control register lives in CSR region, so the offset
of it should be calculated according to CSR region start address.
Without this patch, the offset is calculated according to i.MX8QM/QXP
LVDS subsystem start address.  This patch corrects the offset.
