Rename the file camss-vfe-780.c to camss-vfe-gen3.c to enable
reuse of VFE logic across multiple SoCs.

The lemans(sa8775p) SoC includes VFE 690, which is very similar
to VFE 780, with only minor differences in register bitfields.
Rename prepares the codebase for supporting additional SoCs
without duplicating VFE logic.

Add the compatible string "qcom,sa8775p-camss" to support the
Camera Subsystem (CAMSS) on the Qualcomm lemans platform.

The Lemans(SA8775P) platform provides:
- 2 x VFE (version 690), each with 3 RDI
- 5 x VFE Lite (version 690), each with 6 RDI
- 2 x CSID (version 690)
- 5 x CSID Lite (version 690)
- 4 x CSIPHY (version 690)
- 3 x TPG

Lemans is the first Qualcomm SoC to introduce a CSIPHY-based
Test Pattern Generator (TPG).

Add CAMSS_8775P enum, compatible and lemans(sa8775p) camss driver
private data, the private data just include some basic information
now, later changes will enumerate with csiphy, tpg, csid and vfe
resources.
