SDIO IRQ is not defaultly triggered by low level,
but by falling edge. It needs to set related register
to enable SDIO IRQ low level trigger function.
Otherwise the SDIO IRQ may be lost in some specail condition.

From: yong mao <yong@mediatek.com>
1. Add irqlock to protect accessing the shared register
2. Modify the implementation of msdc_card_busy due to SDIO
3. Implement enable_sdio_irq
4. Add msdc_recheck_sdio_irq mechanism to make sure all
interrupts can be processed immediately

mmc: mediatek: Fix CMD6 timeout issue
From: yong mao <yong@mediatek.com>
When initializing EMMC, after switch to HS400,
it will issue CMD6 to change ext_csd, if first CMD6 got CRC
error, the repeat CMD6 may get timeout, that's
because SDCBSY was cleared by msdc_reset_hw()
