usb: gadget: notify suspend clear to usb phy in udc

When usb composition switch happens from composition containing adb
eg. 9025 to non adb compositions like 905B/9063, usb goes to lpm 
in middle of MBIM/RNDIS protocol transaction. PCNOC crash happens 
when MBIM/RNDIS call ep_queue. 

When usb composition switch happens from non adb composition like F000
to non adb compositions like 905B/9063, then usb goes to lpm before 
usb composition switch complete. Also MBIM/RNDIS protocol transactions 
do not happen.

By notify suspend clear to usb phy in udc, solves the problem.
