Add the SDIO ID and firmware matching for the 43751 device.

Based on the previous work from Marc Gonzalez <mgonzalez@freebox.fr>.

Tested on an i.MX6DL board connected to an AP6398SV chip with the
brcmfmac43752-sdio.bin firmware taken from:

mmc_can_* functions sometimes relate to the card and sometimes to the host.
Make it obvious by renaming this function to include 'host'.

Adds the MMC_QUIRK_NO_UHS_DDR50_TUNING quirk and updates
mmc_execute_tuning() to return 0 if that quirk is set. This fixes an
issue on certain Swissbit SD cards that do not support DDR50 tuning
where tuning requests caused I/O errors to be thrown.

The R1B response type with ignoring CRC is used in the mmc_cqe_recovery(),
introduce the MMC_RSP_R1B_NO_CRC response type to simplify the code.

The MMC_RSP_R1_NO_CRC type of response is not being used by the mmc core
for any commands. Let's therefore drop it, together with the corresponding
code in the host drivers.
