[PATCH 2/6] usb: chipidea: usbmisc_imx: Fix setting i.MX6SX wakeup source

[Sascha Hauer]

MX6SX_USB_VBUS_WAKEUP_SOURCE are two bits containing an enum value,
so when read/modify/write that we have to clear both bits bits before
setting the desired bits. The clearing of the bits was forgotten, add
it.
