Subject: [PATCH 3.10 056/319] ARM: sa1100: clear reset status prior to reboot

From: Russell King <rmk+kernel@...linux.org.uk>

commit da60626e7d02a4f385cae80e450afc8b07035368 upstream.

Clear the current reset status prior to rebooting the platform.  This
adds the bit missing from 04fef228fb00 ("[ARM] pxa: introduce
reset_status and clear_reset_status for driver's usage").

Fixes: 04fef228fb00 ("[ARM] pxa: introduce reset_status and clear_reset_status for driver's usage")
