[RFC PATCH 1/2] spl: enable regulator-boot-on and disable regulator-force-boot-off

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>

This makes sure regulators that need to be turned on or off at boot are
turned on or off in the SPL.

This may be required for the SPL to do some operations, such as finding
possible loading media for U-Boot proper.
