Sergei Ianovich 23f00caf6e ARM: pxa: prevent PXA270 occasional reboot freezes
Erratum 71 of PXA270M Processor Family Specification Update
(April 19, 2010) explains that watchdog reset time is just
8us insead of 10ms in EMTS.

If SDRAM is not reset, it causes memory bus congestion and
the device hangs.

We put SDRAM in selfresh mode before watchdog reset, removing
potential freezes.
