mmc: mediatek: add pre_enable() and post_disable() hook function

Browse source

CQHCI_ENABLE bit in CQHCI_CFG should be disabled
after msdc_cqe_disable(), and should be enabled before
msdc_ceq_enable() for MTK platform.
Add hook functions for cqhci_host_ops->pre_enable() and
cqhci_host_ops->post_disable().
