drm: mxsfb: DRM_MXSFB should depend on ARCH_MXS || ARCH_MXC

[ Upstream commit 7783cc6786 ]

Freescale/NXP i.MX LCDIF and eLCDIF LCD controllers are only present on
Freescale/NXP i.MX SoCs.  Hence add a dependency on ARCH_MXS ||
ARCH_MXC, to prevent asking the user about this driver when configuring
a kernel without Freescale/NXP i.MX support.
