The omapdrm driver relies on this header to be included
implicitly, but this does not always work, and I get
this error in randconfig builds:

gpu/drm/omapdrm/dss/hdmi_phy.c: In function 'hdmi_phy_dump':
gpu/drm/omapdrm/dss/hdmi_phy.c:34:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
gpu/drm/omapdrm/dss/hdmi_wp.c: In function 'hdmi_wp_dump':
gpu/drm/omapdrm/dss/hdmi_wp.c:26:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]
gpu/drm/omapdrm/dss/hdmi_pll.c: In function 'hdmi_pll_dump':
gpu/drm/omapdrm/dss/hdmi_pll.c:30:2: error: implicit declaration of function 'seq_printf' [-Werror=implicit-function-declaration]

This adds the #include statements in all files that have
a seq_printf statement.

Some parts of the OMAP drm driver rely on implicit inclusion of
linux/of.h but fail in some configurations:

drivers/gpu/drm/omapdrm/dss/hdmi4.c: In function 'hdmi_probe_of':
drivers/gpu/drm/omapdrm/dss/hdmi4.c:564:2: error: implicit declaration of function 'of_node_put' [-Werror=implicit-function-declaration]
drivers/gpu/drm/omapdrm/dss/hdmi5.c: In function 'hdmi_probe_of':
drivers/gpu/drm/omapdrm/dss/hdmi5.c:590:2: error: implicit declaration of function 'of_node_put' [-Werror=implicit-function-declaration]

This adds an explicit #include statement to those files.

A lot of the display drivers for OMAP use the gpio descriptor functions
that are only available in linux/gpio.h if GPIOLIB is enabled and
otherwise produce a build error:

drivers/gpu/drm/omapdrm/displays/encoder-opa362.c: In function 'opa362_enable':
drivers/gpu/drm/omapdrm/displays/encoder-opa362.c:101:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration]
drivers/gpu/drm/omapdrm/displays/panel-dpi.c: In function 'panel_dpi_probe_pdata':
drivers/gpu/drm/omapdrm/displays/panel-dpi.c:189:23: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]
drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c: In function 'sharp_ls_enable':
drivers/gpu/drm/omapdrm/displays/panel-sharp-ls037v7dw01.c:120:3: error: implicit declaration of function 'gpiod_set_value_cansleep' [-Werror=implicit-function-declaration]

This replaces the existing linux/gpio.h with linux/gpio/consumer.h
where needed. In case of panel-lgphilips-lb035q02.c however, we
also have to include linux/gpio.h to get the definition of gpio_is_valid
and gpio_set_value_cansleep that are used for the non-DT case.
