ARM: dts: msm: configure PM8998 S5 and S7 for mode pin control on msm8998



Configure PMIC PM8998 SMPS regulators S5 and S7 to use the
PMIC_AWAKE signal for mode pin control.  This ensures that these
regulators are set to auto mode instead of retention mode during
system suspend when RFCLK3_EN is asserted by the 802.11ad
hardware.  This is needed so that WLAN wake works correctly as
the 802.11ad circuitry draws more current than retention mode
supports.
