Ok, thank you for the suggestion.

I'll go with "MICROCHIP PIC64-HPSC/HX DRIVERS" for all the small SoC
drivers (MDIO, GPIO, timers, etc.) and a separate entry for the big things
like RDMA or FRER hw accelerator, if we ever get there.

I won't add anything to RISC-V MICROCHIP SUPPORT even if PIC64-HPSC is
indeed a RISC-V chip since this entry is all Polarfire.

Thanks,
Charles
