Add a header file to prevent build errors:
../drivers/gpu/drm/xlnx/zynqmp_dp.c: In function ‘zynqmp_dp_write’:
../drivers/gpu/drm/xlnx/zynqmp_dp.c:335:9: error: implicit declaration of
function ‘writel’ [-Werror=implicit-function-declaration]
335 | writel(val, dp->iomem + offset);
../drivers/gpu/drm/xlnx/zynqmp_dp.c: In function ‘zynqmp_dp_read’:
../drivers/gpu/drm/xlnx/zynqmp_dp.c:340:16: error: implicit declaration of
function ‘readl’ [-Werror=implicit-function-declaration]
340 | return readl(dp->iomem + offset);
