mmc: fix idx assigning for not aliased sdhci host controllers
Forward porting of 35928d6c6a to 6e9e049fa introduced a bug for host
controllers which are not aliased in the device tree. Instead of
instantiating the driver it fails with:
sdhci-esdhc-imx 2194000.usdhc: sdhci_pltfm_init failed -12
sdhci-esdhc-imx: probe of 2194000.usdhc failed with error -12
