[PATCH v3 5/5] media: qcom: camss: Add support for Hawi

[Nihal Kumar Gupta]

From: Hangxiang Ma <hangxiang.ma@xxxxxxxxxxxxxxxx>

Add CAMSS support for the Hawi SoC. The CSIPHY resource table is reused
from Kaanapali and the TPG table from X1E80100.

Hawi calls its front-end blocks TFEs (Thin Front Ends), but the VFE 1190
driver keeps the VFE naming for consistency. The common CPAS clocks are
managed as PM clocks of the CAMSS resources rather than per-VFE clocks.

CSID 1190 splits RUP and AUP updates into separate registers committed
through a SET register, so the driver provides separate reg_update and
addr_update operations, and VFE 1190 wires up addr_update. The SOF and
EOF INFO bits are also defined.
