ARM: mach-shmobile: mackerel: clarify shdi/mmcif switch settings
* Pins 2 and 4 of switch 33 are documented as don't care on the PCB,
my testing seems to confirm this.
* I have been unable to do anything sensible with S1 set to on.
Am I missing something with regards to MMC1?
* Clarify which driver is needed for each switch setting.
* Should the AP4 board code be updated to allow the
SHDI driver to access SHDI1 as the mackerel code does?
