samus: Change 3.3DSW_GATED to enabled in S0 and disabled in S3

Move the 3.3DSW_GATED rail to be enabled in transition to S0 and
disabled in the transition to S3.

This is the rail for the core regulator and temp sensors so it
does not need to be enabled in S5.

BRANCH=samus
TEST=build and boot on samus, successfully suspend/resume and
ensure that PP3300_DSW_GATED is turned off in S3.
