[PATCH 5.10 159/188] net/mlx5: Fix PPLM register mapping

[Greg Kroah-Hartman]

From: Aya Levin <ayal@xxxxxxxxxx>

[ Upstream commit ce28f0fd670ddffcd564ce7119bdefbaf08f02d3 ]

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")
