[PATCH 1/2][SRU][OEM-5.10/OEM-5.13/OEM-5.14/H/I] igc: Remove _I_PHY_ID checking

[You-Sheng Yang]

From: Sasha Neftin <sasha.neftin at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1945576

i225 devices have only one PHY vendor. There is no point checking
_I_PHY_ID during the link establishment and auto-negotiation process.
This patch comes to clean up these pointless checkings.
