usb: gadget: f_fs: add poll for endpoint 0
This patch adds poll function for file representing ep0.
Ability of read from or write to ep0 file is related with actual state of ffs:
- When desctiptors or strings are not written yet, POLLOUT flag is set.
- If there is any event to read, POLLIN flag is set.
- If setup request was read, POLLIN and POLLOUT flag is set, to allow
send response (by performing I/O operation consistent with setup request
direction) or set stall (by performing I/O operation opposite setup
request direction).
