Move DM355 MMC/SD pinmux to the device setup code; it shouldn't
be coupled to clock activation. This is a small cleanup which
doesn't yet support options like not muxing all MMCSD1 pins when
they're not needed (e.g. hard-wired to an SDIO WLAN adapter).
Such options should be dealt with at the board-*.c level -- as well as any
board level PinMux specifics (say, you need unused pins of some device to be
used by other device and you do need both devices to work).

PS: We now have the code to detect PinMux conflicts at runtime but it will
only work on DM35x. DM64xx PinMux registers are module-, not pin-centric
(i.e., it might be possible to detect conflicts there but that would need
careful work of grouping some separate bitfields together in 'struct
pin_config' to create mutually exclusive configs -- not sure if it's at all
posiible ATM). Hopefully, we'll be able to submit that...
