usb: ehci-msm-hsic: Restore CMD_RUN bit in ehci->command after resume
EHCI driver maintains a copy of USB_CMD contents in ehci->command
variable. CMD_RUN bit is cleared from this variable to delay SOF
till port is resumed. Restore this bit back in ehci->command after
resume is completed otherwise ehci driver may later use stale
ehci->command value to update USB_CMD register clearing CMD_RUN bit.
