sh-mobile: add support for displays, connected over the MIPI bus

Some SH-mobile SoCs have a MIPI DSI controller, that can be used to connect
MIPI displays to LCDC. This patch adds a platform driver for SH-mobile MIPI DSI
unit. It uses existing hooks in the sh_mobile_lcdcfb.c driver for display
activation and deactivation.
