The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID.
CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are
inside the VFE region (between the "top" and "bus" registers), so a
workaround is added to avoid ioremap failure.
[bod] Fixed setting camnoc_axi_clk_src instead of camcc_camnoc_axi_clk
[jgrahsl, bod] Add slow_ahb_src clock values
[jgrahsl, bod] Add cpa_ahb clock values

Add support for VFE found on SM8250 (Titan 480). This implementation is
based on the titan 170 implementation. It supports the normal and lite VFE,
and only supports the RDI0 capture path.

In order to support Qualcomm ISP hardware architectures that diverge
from older architectures, the CSID subdevice drivers needs to be refactored
to better abstract the different ISP hardware architectures.

Add register definitions for version 170 of the Titan architecture
and implement support for the RDI output mode.
The RDI mode as opposed to the PIX output mode for the VFE unit does
not support any ISP functionality. This means essentially only
supporting dumping the output of the whatever the CSI decoder receives
from the sensor.
For example will a sensor outputting YUV pixel format frames, only
allow the VFE to dump those frames as they are received by the ISP
to memory through the RDI interface.

Gen1 represents the CAMSS ISP architecture. The ISP architecture developed
after CAMSS, Titan, will be referred to as Gen2.
