net: ethernet: stmmac: Fix signedness bug in ipq806x_gmac_of_parse()
[ Upstream commit 231042181dc9d6122c6faba64e99ccb25f13cc6c ]
The "gmac->phy_mode" variable is an enum and in this context GCC will
treat it as an unsigned int so the error handling will never be
triggered.
Fixes: b1c17215d718 ("stmmac: add ipq806x glue layer")
