usb: phy: mxs: fix getting wrong state with mxs_phy_is_otg_host()
The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is
0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real
state if the ID pin is float, such as Host-only or Type-C cases. The value
of OTG_ID_VALUE is always 1 which means device mode.
This patch will fix the issue by judging the current mode based on
last_event. The controller will update last_event in time.
