[PATCH 28/45] configs: j721s2_evm_a72_defconfig: Increase aneg timeout to 20000 ms

Increase the PHY Auto-Negotiation timeout to 20,000 ms from the current
default of 4,000 ms inherited from "Kconfig" for PHY_ANEG_TIMEOUT.

The motivation for this change is that existing devices will continue
working as-is (timeout is an upper bound and auto-negotiation can be
done earlier), while older Hardware connected to the board that might
occasionally take longer than 4,000 ms for the Auto-Negotiation process
will benefit from an increased timeout.
