Add <linux/io.h> header to pull in readl/writel and friends.
This eliminates the following build errors:
drivers/gpu/drm/msm/dp/dp_panel.c: In function 'msm_dp_read_link':
drivers/gpu/drm/msm/dp/dp_panel.c:33:16: error: implicit declaration of
function 'readl_relaxed' [-Wimplicit-function-declaration]
33 | return readl_relaxed(panel->link_base + offset);
drivers/gpu/drm/msm/dp/dp_panel.c: In function 'msm_dp_write_link':
drivers/gpu/drm/msm/dp/dp_panel.c:43:9: error: implicit declaration of function
'writel' [-Wimplicit-function-declaration]
43 | writel(data, panel->link_base + offset);
Fixes: d7e3bee925bd ("drm/msm/dp: drop the msm_dp_catalog module")
