[ARM] orion5x: Fix soft-reset for some platforms
Some platforms, such as the DNS-323 rev C requires the soft reset line
to be toggled on and back off for the reset to work.
Note: The choice of 200ms delay comes from the 2.6.12 based vendor kernel.
It seems to be a -lot- though and I had my device working fine with much
smaller delays but better safe...
