[PATCH 6/8] ARM: OMAP5: hwmod_data: Add data for IPU & DSP processors

OMAP5, like OMAP4, also has an IPU and a DSP processor subsystems.
The relevant hwmod classes and data structures are added for these
devices.

Do note that these hwmod data strucutures do not have a .modulemode
field as the devices are managed together with their corresponding
MMUs. Each of the processor subsystem and its MMU are present within
the same clock domain and requires the domain be clocked and enabled
until the last entity is disabled. The module is disabled properly
during the omap_device_idle processing of the MMU hwmod while
disabling the MMU.
