Jonas Gorski 01796e87b1 ar71xx: rb493g: fix gpio-mdio accesses under load ...

It seems that there are maximum timings for mdio accesses that can be
hit when the system is under load and the thread is scheduled during
a read or write access. Since there is no way of knowing if this
happens as there is not even a parity bit, try to work around it
by disabling interrupts during any gpio-mdio accesses.

Performance impact seems to be neglectable, as mdio accesses are not
that often.

Hopefully fixes #19500.
