To enable PMU with runtime PM support on OMAP3 devices we need to be able to
dynamically enable and disable the debug sub-system at runtime. By adding HWMOD
data for the debug sub-system for OMAP3, we can build the PMU device using the
debug sub-system HWMOD and control this power domain using runtime PM.

Isn't this patch missing MPU address ranges?  Looking at the OMAP4 TRM 
Table 2-2 "L3_EMU Memory Space Mapping" it should cover 
0x54000000-0x541fffff?
