OMAP3 hwmod: reprogram OCP_SYSCONFIG register after setting SOFTRESET

Browse Source 
Reprogram the module's OCP_SYSCONFIG register after module reset (SOFTRESET
= 1).  This may not be needed, but the definition of the reset performed by
the SOFTRESET bit is unclear.

Kevin Hilman <khilman@deeprootsystems.com> tested an earlier version of
this patch.
