max3421: prevent USB host hang at startup
On some boards the MAX3421E doesn't report its oscillator ready after a
soft reset (CHIPRES), so hcd_init() waits on USBIRQ_OSCOK forever and the
host hangs at startup before any USB device can be used. Bound the wait so
it proceeds after a timeout; it is a no-op where OSCOK arrives normally.
Needed on the Adafruit Feather ESP32 V2 (classic ESP32) + USB Host
FeatherWing, which otherwise hangs on essentially every cold boot.
Relates to adafruit/circuitpython#10053.
