media: qcom: camss: Start to move to module compat matched resources

There is a lot of unnecessary if/elsing in this code that arguably
should never have made it upstream when adding a second let alone
subsequent SoC.

I'm guilty of not fixing the mess myself when adding in the sm8250.
Before adding in any new SoCs or resources lets take the time to cleanup
the resource passing.

First step is to pass the generic struct camss_resources as a parameter
per the compatible list.

Subsequent patches will address the other somewhat disparate strutures
which we are also doing if/else on and assigning statically.

Squashed down a commit to drop useless NULL assignment for ispif resources.
