Simon Glass d5cb026142 Enable checking for divide by 0 and alignment faults ...

These likely indicate errors, so we shold trap them. Possibly this
should be reconsidered for production.

BUG=chrome-os-partner:10148
TEST=manual:
build on all boards
build and boot on snow with a special rw command containing a division
by 0. See that it is trapped:
> rw 0

=== EXCEPTION: 03 ====== xPSR: 01000000 ===========
r0 :0000000b r1 :08005eba r2 :00000000 r3 :20001048

Divide by 0, Forced hard fault, Vector catch
mmfs = 02000000, shcsr = 00000000, hfsr = 40000000, dfsr = 00000008

Turn off the cpu_init() setup, and see that it is ignored.

> rw 0
read 0x0 = 0x00000000
>

Similarly, try an unaligned access with the rw command with this enabled:

> rw 1

=== EXCEPTION: 03 ====== xPSR: 01000000 ===========

Unaligned, Forced hard fault, Vector catch
mmfs = 01000000, shcsr = 00000000, hfsr = 40000000, dfsr = 00000008

but disabled it works:

> rw 1
read 0x1 = 0x5d200010
