sd-as3525v2: working transfers, still awfully slow
...
not touching MCI_CTYPE (leaving bus width to 1) gives data transfers
ignore the hardware locked up while error bit for now
remove printf() helper & debug code

sd-as3525v2: panic in case of error in the isr
...
Disable errors on response timeout since it can happen on SD_SEND_IF_COND
Disable errors on start bit error : it's ignored by the linux driver
No panic on my side with those 2 bits unchecked, but no transfer
completion either.
Note: the Linux driver doesn't implement DMA

sd-as3525v2: describe interrupt mask bits
...
Reset DMA before transfers and check data transfer over bit in isr
Still no error or data transfer over conditions
Read the correct status register in isr : there is a masked interrupt
status register and a general status register
