MMCI: Fix incorrect handling of HW FC for SDIO

For SDIO writes smaller than or equal to 8 bytes (only SDIO case),
hardware flow control was turned off, but was never turned on again
which meant that if a large read request followed, SDIO would randomly
give buffer overrun errors since there was no flow control.

Since HW flow control is not really needed for anything that fits in the
HW FIFO of PL18X, HW flow control is now disabled for any write
operation that is smaller than or equal to the FIFO size.
