[ Upstream commit 861b67fbdccd62a9319d7350b1924d95f597db09 ]
According to the downstream device tree, the regulator that powers the
I/O for eMMC should not be turned off. Keep it always on just in case
the eMMC driver fails and doesn't enable it, or unloads and disables it.
Fixes: 07c8ded6e373 ("arm64: dts: qcom: add sdm670 and pixel 3a device trees")
