mmc: mediatek: command queue support
Support command queue for mt6779 platform.
a. Add msdc_set_busy_timeout() to calculate emmc write timeout.
b. Connect mtk msdc driver to cqhci driver through
host->cq_host->ops = &msdc_cmdq_ops;
c. msdc_cmdq_irq() will link up with cqchi_irq(). Besides, it provides
more irq error messages like RSPCRCERR/CMDTO/DATACRCERR/DATTMO.
d. Select kernel config MMC_CQHCI for MMC_MTK
