mbed_die: Use wait_us not wait_ms 

mbed_die was calling wait_ms in a critical section - this is deprecated
behaviour, and caused a fatal error in debug builds, potentially leading
to an infinite reboot loop if this was caused due to a reboot limit
halt.

Switch to using wait_us - this is safe in a critical section. This does
trigger a call to mbed_warning, due to the large parameter, but that is
harmless - it doesn't output anything to the console, and won't
overwrite the error context if it already contains something.
