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. Signed-off-by: Krzysztof Kozlowski --- Changes since v1: 1.
