robert-hh 2a38531d73 samd/mcu: Reduce the startup time after hard reset.
With Crystal: set the crystal startup wait time to 1 second.  It was 2
seconds before, and that seeemed too long.

With USB-Sync: scan for up to 1 second for the USB to be registered and
carry on with boot as soon as it it.  Before, the code just waited for
500ms.

Side change: improve related comments.
