net: phy: meson-gxl: fix interrupt handling in forced mode
This PHY doesn't support a link-up interrupt source. If aneg is enabled
we use the "aneg complete" interrupt for this purpose, but if aneg is
disabled link-up isn't signaled currently.
According to a vendor driver there's an additional "energy detect"
interrupt source that can be used to signal link-up if aneg is disabled.
We can safely ignore this interrupt source if aneg is enabled.
This patch was tested on a TX3 Mini TV box with S905W (even though
boot message says it's a S905D).
This issue has been existing longer, but due to changes in phylib and
the driver the patch applies only from the commit marked as fixed.
