Subject: igc: Remove phy->type checking
Patch-mainline: v5.15-rc1
Git-commit: 47bca7de6a4fb8dcb564c7ca14d885c91ed19e03
References: jsc#SLE-18377

i225 devices have only one phy->type: copper. There is no point checking
phy->type during the igc_has_link method from the watchdog that
invoked every 2 seconds.
This patch comes to clean up these pointless checkings.
