mmc: sdhci-esdhc-imx: separate 100/200 MHz pinctrl states check
As indicated by function esdhc_change_pinstate(), SDR50 and DDR50
require pins_100mhz, while SDR104 and HS400 require pins_200mhz. Some
system design may support SDR50 and DDR50 with 100mhz pin state only
(without 200mhz one). Currently the combined 100/200 MHz pinctrl state
check prevents such system from running SDR50 and DDR50. Separate the
check to support such system design.
