On SM8650, the minimum voltage corner supported on MMCX from cmd-db is
sufficient for clock controllers to operate and there is no need to specify
the required-opps. Hence remove the required-opps property from the list of
required properties for SM8650 camcc and videocc bindings.

This fixes:
arch/arm64/boot/dts/qcom/sm8650-mtp.dtb: clock-controller@aaf0000:
'required-opps' is a required property

arch/arm64/boot/dts/qcom/sm8650-mtp.dtb: clock-controller@ade0000:
'required-opps' is a required property

Changes in V3:
 - Made only required-opps property conditional and added it based on the variant
 - Link to V2: https://lore.kernel.org/all/20240720052818.26441-1-quic_jkona@quicinc.com/
Changes in V2:
 - Made required: conditional and dropped required-opps from it only for SM8650 platform
 - Dropped Krzysztof Acked-by tag due to above changes
 - Link to V1: https://lore.kernel.org/all/20240708130836.19273-1-quic_jkona@quicinc.com/

Why would required-opps be invalid for SM8650? What if we want some
higher opp for some reason? The point of v1 and v2 was oonly to require
required-opps on certain variants, not to disallow it in other cases.

Best regards,
Krzysztof

Also, these should be two separate commits. Each fix for one issue is
one logical change.

Thanks Krzysztof for your review.

Sure, will split this into two separate commits.

Thanks,

Thanks Krzysztof for your review.

Yes, agree, will drop the else part in next series.
