For some MMC cards over SPI bus, it needs to lock the SPI bus for its own

Make sure we don't leak peripheral/gpio resources when an error occurs
during setup, and make sure we don't call kfree() twice on the same
object. Also add/fix some error messages in the process.

Re-order setup() a bit so we don't leak memory/dma/gpio resources upon

We should make sure the SPI controller is in a sane state in case the
boot loader left it in a crappy state. Such as DMA pending which causes
interrupts to fire on us.
