Dependency to MCHP_MRP not covered by kconfig

[AlbrechtL]

We integrated your Microchip kernel into our custom Linux distribution.

During development we we had the situation that MCHP_MRP was set to n which results in many undefined references to your mrp API. After enabling MCHP_MRP=y this was gone. It seems that some microchip drivers are depending on MCHP_MRP which is not covered by kconfig.

@AlbrechtL: Thanks for reporting this.

I think this may have been caused by a mix of Appl (XSTAX) and Standalone (Switchdev) settings in he same configuration.

The drivers/net/ethernet/microchip/sparx5/Kconfig file selects MCHP_MRP for SPARX5_SWITCH which is the switchdev driver that provides the MRP implementation.
