[PATCH v6 27/28] media: iris: enable video driver probe of SM8250 SoC

[Dikshita Agarwal <quic_dikshita@quicinc.com>]

Initialize the platform data and enable video driver probe of SM8250
SoC. Add a kernel param to select between venus and iris drivers for
platforms supported by both drivers, for ex: SM8250.
