Uwe Kleine-König 3f18b1bf59 ARM: make isa_mode macro more robust and fix for v7-M 
The definition of isa_mode hardcodes the values to shift PSR_J_BIT and
PSR_T_BIT to move them to bits 1 and 0 respectively. Instead use __ffs to
calculate the shift from the #define already used for masking.

This is relevant on v7-M as there PSR_T_BIT is 0x01000000 instead of
0x00000020 for V7-[AR] and earlier. Because of that isa_mode produced
values >= 0x80000 which are unsuitable to index into isa_modes[4] there
and so made __show_regs read from undefined memory which resulted in
hangs and crashes.

Moreover isa_mode is wrong for v7-M even after this robustness fix as
there is no J-bit in the PSR register. So hardcode isa_mode to "Thumb"
for v7-M.
