usb: bdc: fix sleep during atomic
[ Upstream commit f1195ca3b4bbd001d3f1264dce91f83dec7777f5 ]
bdc_run() can be ran during atomic context leading to a sleep during
atomic warning. Fix this by replacing read_poll_timeout() with
read_poll_timeout_atomic().
Fixes: 75ae051efc9b ("usb: gadget: bdc: use readl_poll_timeout() to simplify code")
