Subject: [PATCH] drm/bridge: imx: i.MX8 bridge drivers should depend on ARCH_MXC

The various Freescale i.MX8MP display bridges are only present on
Freescale i.MX8 SoCs.  Hence add a dependency on ARCH_MXC, to prevent
asking the user about these drivers when configuring a kernel without
i.MX SoC support.

Fixes: e60c4354840b2fe8 ("drm/bridge: imx: Add LDB support for i.MX8qm")
Fixes: 3818715f62b42b5c ("drm/bridge: imx: Add LDB support for i.MX8qxp")
Fixes: 96988a526c97cfbe ("drm/bridge: imx: Add i.MX8qxp pixel link to DPI support")
Fixes: 1ec17c26bc06289d ("drm/bridge: imx: Add i.MX8qm/qxp display pixel link support")
Fixes: 93e163a9e0392aca ("drm/bridge: imx: Add i.MX8qm/qxp pixel combiner support")
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>

Probably the remaining i.MX bridge drivers in
drivers/gpu/drm/bridge/Kconfig (e.g. DRM_FSL_LDB) should be moved here,
too?
