ARM: DRA7: hwmod_data: add data for IPU and DSP1 rprocs

The DRA7xx family of SoCs usually have two IPU and up to two DSP
remote processor subsystems. These subsystems are very similar to
the respective processor subsystems on OMAP4/OMAP5 in terms of clock
and reset integration. The relevant hwmod classes and data structures
are added for IPU1, IPU2 and DSP1 remoteproc devices, the most common
processors present on all DRA7xx SoCs.

Do note that these hwmod data structures 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.
