MXSCM-217 imx: keep weak 2p5 power up when ENET WOL wakeup is enabled

When ENET wake up is enabled by wake-on-lan (WOL), the weak 2P5
ldo needs to keep power up even for LPDDR2 due to the ENET_PLL is
feed by the weak 2p5 ldo during DSM. If the weak 2P5 ldo is power
down the ENET module is power off hence it is not able to sense the
WOL interrupt and trigger the system resume.
