[ARM] Move processor_modes[] to .../process.c

Browse Source 
bad_mode() currently prints the mode which caused the exception, and
then causes an oops dump to be printed which again displays this
information (since the CPSR in the struct pt_regs is correct.)  This
leads to processor_modes[] being shared between traps.c and process.c
with a local declaration of it.

We can clean this up by moving processor_modes[] to process.c and
removing the duplication, resulting in processor_modes[] becoming
static.
