Subject: [net 4/5] net/mlx5: Fix PBMC register mapping

From: Aya Levin <ayal@...dia.com>

Add reserved mapping to cover all the register in order to avoid setting
arbitrary values to newer FW which implements the reserved fields.

Fixes: 50b4a3c23646 ("net/mlx5: PPTB and PBMC register firmware command support")
