bool is not a good choice here, because if ESDHC_IMX is selected as a
module (-m), it will get converted here to built-in (-y). Same goes for
MMC_SDHCI_PLTFM. If I change both into tristate and then compile, I get
a build error:

ERROR: "sdhci_pltfm_suspend" [drivers/mmc/host/sdhci-esdhc.ko] undefined!
ERROR: "sdhci_get_of_property" [drivers/mmc/host/sdhci-esdhc.ko] undefined!
ERROR: "sdhci_pltfm_init" [drivers/mmc/host/sdhci-esdhc.ko] undefined!
ERROR: "sdhci_pltfm_free" [drivers/mmc/host/sdhci-esdhc.ko] undefined!

So, the module-support seems to be missing for the library.

Regards,
