Blackfin: replace "bfin_reset_or_hang()" with "panic()"

Browse source 
The bfin_reset_or_hang function unnecessarily duplicates the panic()
logic based on CONFIG_PANIC_HANG.

This patch deletes 20 lines of code and just calls panic() instead.
This also makes the following generic-restart conversion patch simpler.
