MLK-10188 arm: imx: Add dummy LDO2p5 regulator for VBUS wakeup
LDO2p5 cannot be disabled in low power idle mode when the USB driver
enables VBUS wakeup. To identify when LDO2p5 can be disabled add a dummy
regulator that the USB driver will enable when VBUS wakeup is required.
This patch is copied from commit 7d849e4d9ebca3c as code the structure has
changed too many. directly cherry-pick has too many conflicts to resolve

(cherry picked from commit 25a42aeb8eeb0b894a70e1a0f6750ced39830a46)
