Randall Spangler acf6f963a1 Flash pre-init reboots if it needs to clear protection registers ...

BUG=chrome-os-partner:11171
TEST=manual

1. Clear some of the writable-bits in the flash registers
> ww 0x400fe40c 0xffff1234
write 0x400fe40c = 0xffff1234
> rw 0x400fe40c
read 0x400fe40c = 0xffff1234
2. Reset using power+refresh
3. Register should be clear again
> rw 0x400fe40c
read 0x400fe40c = 0xffffffff
4. Sysinfo should indicate reset-pin reason AND hard-reset reason
> sysinfo
Reset flags: 0x0000000a (reset-pin power-on)
5. Reset using power+refresh
6. Sysinfo should indicate reset-pin reason only
> sysinfo
Reset flags: 0x00000002 (reset-pin)
7. Clear writable-bits again
> ww 0x400fe40c 0xffff1234
write 0x400fe40c = 0xffff1234
8. Jump to another image.  This should NOT trigger a hard reset.
> sysjump A
> sysinfo
Reset flags: 0x00000402 (reset-pin sysjump)
