[PATCH net-next 2/2] stmmac: intel: Enable 2.5Gbps on Intel AlderLake-S

[Wong Vee Khee <vee.khee.wong@linux.intel.com>]

From: Michael Sit Wei Hong <michael.wei.hong.sit@intel.com>

Intel AlderLake-S platform is capable of 2.5Gbps link speed.

This patch enables the 2.5Gbps link speed by adding the callback
function in the AlderLake-S PCI info struct.
