Vincent Palatin 1f7961e693 ryu: workaround MAX77620 shutdown issue ...

When shutting down the MAX77620 PMIC by asseting its SHDN pin, the
EN_PP3300 output of the PMIC (GPIO3) is not going off keeping the PP3300
rail up. Workaround that issue by removing the pull-up on EN_PP3300 when
we assert SHDN.

TEST=on a P5 board, type "apshutdown" and see the power state machine
going to S5, type "powerbtn" and see it going back to S0.
