board: samsung: odroid: drop exynos_power_init

Browse Source 
exynos_power_init sets up regulators for the emmc and sdcard, but
these regulators are already marked as always-on and boot-on and hence
are handled already by the regulator-uclass. Since we currently try to
set them up twice we get error -114 (EALREADY) from exynos_power_init
on every boot:

    LDO20@VDDQ_EMMC_1.8V: set 1800000 uV; enabling (ret: -114)
    LDO22@VDDQ_EMMC_2.8V: set 2800000 uV; enabling (ret: -114)
    LDO21@TFLASH_2.8V: set 2800000 uV; enabling (ret: -114)

Remove the superfluous exynos_power_init to silence these errors.
