The register naming convention for clock domain control inside
power domain instance is:
OMAPXXXX_<partition>_<power_domain>_<clock_domain>_CDOFFS

Both CPU0 and CPU1 use MPU as clock domain name instead of CPU0
and CPU1.

Change the name to stick to the convention.
The autogen scripts are updated accordingly.
