arm/dt: msm8974: Update always-on and lpm-sup SDHC properties

This change applies the following legacy SDCC commits to SDHC -
65b5b7b and bc97c32.

This change marks internal eMMC vdd regulator as always-on to work
around card detection issues when MSM reset is issued via JTAG and
removes external SD card vdd-io regulator as always-on to increase
power savings.
