Neil Armstrong 1cf084d161 usb: dwc3: meson-g12a: fix suspend resume regulator unbalanced disables 
When going in suspend, in Device mode, then resuming back leads
to the following:

unbalanced disables for USB_PWR_EN
WARNING: CPU: 0 PID: 163 at ../drivers/regulator/core.c:2590 _regulator_disable+0x104/0x180
Hardware name: Amlogic Meson G12A U200 Development Board (DT)
[...]
pc : _regulator_disable+0x104/0x180
lr : _regulator_disable+0x104/0x180

Call trace:

 irq_thread+0x118/0x1b8

This disables the regulator if enabled on suspend, and the reverse on
resume.
