From: Paul Walmsley <paul@pwsan.com>

Many of the IP blocks with PRM hardreset lines are processor IP blocks
and need special reset handling to ensure that WFI/HLT-like
instructions are executed after reset. (This special handling ensures that
the IP blocks' bus initiator interfaces indicate that they are in standby
to the PRCM - thus allowing power management for the rest of the chip to
work correctly.)
Use HWMOD_CUSTOM_HARDRESET flags in the hwmod data for IP blocks that
require special reset handling.
