armv8: ls1012a: define esdhc_status_fixup for QDS board
The LS1012AQDS board has a hardware issue. When there is no eMMC
adapter card inserted in SDHC2 adapter slot, the command inhibit
bits of eSDHC2_PRSSTAT register will never release. This would cause
below continious error messages in linux since it uses polling mode
to detect card.
"mmc1: Controller never released inhibit bit(s)."
"mmc1: Controller never released inhibit bit(s)."
"mmc1: Controller never released inhibit bit(s)."
This patch is to define esdhc_status_fixup function for QDS to
disable SDHC2 status if no eMMC adapter card is detected.
