ARM: AM43XX: hwmod: Fix RSTST register offset for pruss

BugLink: http://bugs.launchpad.net/bugs/1627730
commit b00ccf5b684992829610d162e78a7836933a1b19 upstream.

pruss hwmod RSTST register wrongly points to PWRSTCTRL register in case of
am43xx. Fix the RSTST register offset value.

This can lead to setting of wrong power state values for PER domain.
