ENGR00234933 mmc: sdhci: invalid cd_gpio for always_present host controller

Issue:
By default, cd_gpio is 0 for always presented host controller, which is a
valid gpio. Then it will result to free_irq for 0 in esdhc_pltfm_exit for
these always_present host controllers.

Fix:
Invalid cd_gpio if the controller is indicated to be always present.
