[PATCH v4 04/12] platform_data/mlxreg: Add capability bit and mask fields

[Vadim Pasternak <vadimp@nvidia.com>]

Some 'capability' registers can be shared between different resources.
Add new fields 'capability_bit' and 'capability_mask' to structs
'mlxreg_core_data' and 'mlxreg_core_item' for getting only relevant
capability bits.
