Subject: net/mlx5: Fix PPLM register mapping
Patch-mainline: v5.12-rc7
Git-commit: ce28f0fd670ddffcd564ce7119bdefbaf08f02d3
References: jsc#SLE-8464

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

Fixes: a58837f52d43 ("net/mlx5e: Expose FEC feilds and related capability bit")
