USB: ci13xxx_udc: Don't flush and disable all endpoints during disconnect
Flushing and disabling all endpoints during disconnect in controller
driver is simply wasteful and unnecessary. Flushing endpoints before
notifying disconnect to composite driver will have side effects too.
The active endpoints will be disabled by function drivers when they
notified about disconnect.
The current code use 100 msec timeout for flush operation. If controller
driver flush and disable all endpoints, the worst case timeout will be
added up to several seconds. This is leading to watch dog timeout.
