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

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