mmc: cmdq_hci: Notify sdhci for enhanced strobe
Provide cmdq_host ops of enhanced strobe to notify
sdhci on enabling/disabling cmdq. This is needed
because of following:
Before running CMDQ transfers in HS400 Enhanced Strobe mode,
SW should write 3 to
HC_VENDOR_SPECIFIC_FUNC3.CMDEN_HS400_INPUT_MASK_CNT register.
Default reset value of this register is 2.
