Subject: net: phylink: Fix phylink_dbg() macro
Patch-mainline: v5.4-rc6
Git-commit: 9d68db5092c5fac99fccfdeab3f04df0b27d1762
References: bsc#1154353 bnc#1151927 5.3.10

The phylink_dbg() macro does not follow dynamic debug or defined(DEBUG)
and as a result, it spams the kernel log since a PR_DEBUG level is
currently used. Fix it to be defined appropriately whether
CONFIG_DYNAMIC_DEBUG or defined(DEBUG) are set.

Fixes: 17091180b152 ("net: phylink: Add phylink_{printk, err, warn, info, dbg} macros")
