Subject: [PATCH v2] i2c: cpm: Remove linux,i2c-index conversion from be32

sparse reports an error on some data that gets converted from be32.

That's because that data is typed u32 instead of __be32.

The type is correct, the be32_to_cpu() conversion is not.

Remove the conversion.

v2: Use u32 directly, remove be32_to_cpu().
