net: phy: aquantia: only poll GLOBAL_CFG regs on aqr113, aqr113c and aqr115c

Browse source

Commit 708405f3e5 ("net: phy: aquantia: wait for the GLOBAL_CFG to
start returning real values") introduced a workaround for an issue
observed on aqr115c. However there were never any reports of it
happening on other models and the workaround has been reported to cause
and issue on aqr113c (and it may cause the same on any other model not
supporting 10M mode).

Let's limit the impact of the workaround to aqr113, aqr113c and aqr115c
and poll the 100M GLOBAL_CFG register instead as both models are known
to support it correctly.
