mmc: core: Imply IOSCHED_BFQ

Browse Source 
If we enable the MMC/SD block layer, use Kconfig to imply the BFQ
I/O scheduler.

As all MMC/SD devices are single-queue, this is the scheduler that
users want so let's be helpful and make sure it gets
default-selected into a manual kernel configuration. It will still
need to be enabled at runtime (usually with udev scripts).
