mmc: hi6220_dw_mmc: add fifoth_val to private data and set it in .probe
The value defaults to 0 and is ignored by dw_mmc code, so the other
users are not affected.
Setting this explicitly fixes some weird reading error found on Hi3798MV200.
Fixes: 8a5dc8140e62 ("mmc: hi6220_dw_mmc: add compatible for HC2910 support")
