Subject: [Patch 3/6] ARM: OMAP: DRA7xx: Make CAM clock domain SWSUP only

HWSUP on this domain is only working when VIP1 probes.
If only VIP2 on DRA74x or CAL on DRA72x probes the domain does
not get enabled. This might indicates an issue in the HW Auto
state-machine for this domain.

Work around is to set the CAM domain to use SWSUP only.
