ARM: dts: exynos: Use proper regulator for eMMC memory on Arndale Octa
The eMMC memory is supplied by LDO18 (PVDD_EMMC_1V8) and buck10
(PVDD_EMMCF_2V8), not by LDO10. The LDO10 (PVDD_PRE_1V8) supplies
instead VDDP_MMC pin of eMMC host interface and it is already marked as
always on.
This change only properly models the hardware and reflects in usage of
regulators. There is no functional change because:
1. LDO18 cannot be turned off (e.g. by lack of consumers) because in
off mode it is controlled by LDO18EN pin, which is pulled up by
always-on regulator LDO2 (PVDD_APIO_1V8).
2. LDO10 is marked as always on so removing its consumer will not have
effect.
