When CONFIG_QCOM_UBWC_CONFIG=n, compiler needs to know the definition
of ERR_PTR otherwise there will be a compilation error:

In file included from drivers/gpu/drm/msm/disp/dpu1/dpu_hw_sspp_v13.c:7:
./include/linux/soc/qcom/ubwc.h: In function ‘qcom_ubwc_config_get_data’:
./include/linux/soc/qcom/ubwc.h:45:16: error: implicit declaration of
function ‘ERR_PTR’ [-Wimplicit-function-declaration]

Fix this by including <linux/err.h>
