Subject: [PATCH] drm: omap dss: add missing includes

The omapdrm dss driver currently fails to build in some configurations when
the pinctrl and seq_print declarations are not visible:

omapdrm/dss/dss.c:1268:2: error: implicit declaration of function 'pinctrl_pm_select_sleep_state' [-Werror=implicit-function-declaration]
omapdrm/dss/dss.c:1277:2: error: implicit declaration of function 'pinctrl_pm_select_default_state' [-Werror=implicit-function-declaration]
omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]

This adds the appropriate include statements.

Found on ARM randconfig builds. I assume there are also configurations in which this is
not needed because the headers get included through other headers, and I have not
investigated exactly what options cause this as the fix seems obvious and harmless.
