Both fb and mmc will need operable clock control to function.  mmc
will also need the vreg code (to adjust power to the sdcard slot).
Both clk_* and vreg_* are already in, though I haven't put them
through their paces in the latest kernel tree.  They both just wrap
proc_comm (as the modem owns both clock and power control) and are
pretty simple -- they should "just work".

The framebuffer is "fun" to bootstrap -- it needs the mddi transport
(serial video interface), mddi-to-lcdc bridge and panel init code, and
the mdp dma code to go.
