Yuanjie Yang b4f6aa1666 mmc: sdhci-msm: Correctly set the load for the regulator ...

[ Upstream commit 20a0c37e44063997391430c4ae09973e9cbc3911 ]

Qualcomm regulator supports two power supply modes: HPM and LPM.
Currently, the sdhci-msm.c driver does not set the load to adjust
the current for eMMC and SD. If the regulator dont't set correct
load in LPM state, it will lead to the inability to properly
initialize eMMC and SD.

Set the correct regulator current for eMMC and SD to ensure that the
device can work normally even when the regulator is in LPM.
