MLK-9606-2 usb: otg: test: start tst_maint timer and set otg_vbus_off flag
This patch adds 2 variables: tst_maint and otg_vbus_off, tst_maint is to check if
current session for test device; otg_vbus_off is to notify if A device need turn
off vbus immediately after B device disconnects.
The otg test device handling is added into ehset driver, for that device,
A-device should start a timer for maintain the session, and set otg_vbus_off
flag according to its bcdDevice value.
