We now don't wait FIFO status at the end of request but
at the beginning of upcoming request, which is the same way
we did for unbusy check in the past. By doing that, we can
hand out cpu.

The dwc2_queue_transaction() do data transfer for DMA
mode if both the params.host_dma and chan->qh are true.
In a test-case with an otg cable hot plug stress test
in DMA mode, if the chan->qh is NULL, it is possible to
do dwc2_hc_write_packet() which should only be called
in Slave mode and cause a crash:

1. We always use dma for sdmmc, and it could not be used as SDIO
2. restore affected registers includes ctype and timeout
3. expose API for ISP/VICAP usage
4. remove SD3.0 support which won't affect write throughput
5. limit ffaa0000 controller only be used as sd card before ECO
6. reserve a descriptor for dirty data, in order to let DMA finish
the prior descriptors and the dirty data in the last descriptor will
not be sent at all.
7. use CMD12 + reset to clean the remain dirty data and recovery IP
