If mmc_of_parse() is used, dw_mci_of_get_cd_gpio didn't need.
Already implemented into mmc_of_parse().

Can be this done in 2/8(mmc: dw_mmc: use the mmc_of_parse() instead of local parser) together?
Additionally we have a chance to remove 'write protect gpio' part including dw_mci_of_get_wp_gpio() now.
mmc_of_parse() also has those.
Can you address more?

Thanks,
Seungwon Jeon

Sure! It can be removed also. I will update it.
