Enable a couple of CAPS that qcom sd host controller supports.
Set a quirk for enabling support for auto cmd12.
And enable adma length mismatch error interrupt.

MSM sd host controller is capable of HW busy detection of device busy
signaling over DAT0 line. And it requires the R1B response for
commands that have this response associated with them.
So set the below two host capabilities for qcom SDHC.
- MMC_CAP_WAIT_WHILE_BUSY
- MMC_CAP_NEED_RSP_BUSY

sdhci-msm can support auto cmd12.
So enable SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 quirk.

ADMA_ERR_SIZE_EN bit of VENDOR_SPECIFIC_FUNC register controls
ADMA length mismatch error interrupt. Enable it by default.
And update all bit shift defines with BIT macro.
