Revert "usb: gadget: composite: enable BESL support"

Commit a6615937 ("usb: gadget: composite: enable BESL support")
enables LPM L1 support and advertises this capability to host. It
has been observed that when host is supporting LPM L1 functionality
and triggering it, device controller goes into L1 state but software
is not able to get controller out of L1 state using Link Recovery
functionality which results into USB enumeration issue with host.
Hence to fix this issue disable LPM L1 support from device side.
