[PATCH 2/5 v3] fbdev: sh_mobile_meram: Enable/disable MERAM along with LCDC

[PATCH 2/5 v3] fbdev: sh_mobile_meram: Enable/disable MERAM along with LCDC

[Damian Hobson-Garcia]

The MERAM reference counts should be tied to the two LCDC devices (LCD/HDMI)
so that when they are enable/disabled, the MERAM is as well.

Changes from V2
=======
* Change the names of the clk_on/clk_off callbacks to pm_get_sync/pm_put_sync
  to better reflect their actual functionality
