mmc: sdhci-spear: remove support for power gpio
None of this code is currently used: there are no definitions of struct sdhci_plat_data in arch/arm, neither are there any DT properties which use card_power_gpio/power_active_high/power_always_enb. In any case, slot power control should be rigged up via vmmc and the regulator subsystem in the DT case.
