mmc: au1xmmc: force non-modular build and remove symbol_get usage
commit d4a5c59a955bba96b273ec1a5885bada24c56979 upstream.

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,
and callbacks in platform_data that sit under arch/mips/ and are
always built in.  The latter than call mmc_detect_change through
symbol_get.  Remove the use of symbol_get by requiring the driver
to be built in.  In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.
