Blackfin arch: update printk to use KERN_EMERG and reformat crash output

to look like: return address: [0x0357fcc4]; contents of: 0x0357fca0: fcbc 0357 fe20 0357 0009 0000 6a8c 0345 0x0357fcb0: 000e 0000 fcc4 0357 fd44 0357 e128 00ad 0x0357fcc0: 00a0 0000 [000e] 0000 0000 0000 0080 0000 0x0357fcd0: 0000 0000 0000 0000 00a0 0000 000e 0000 instruction in [] is the offending instruction Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
