[PATCH] ARM: dts: BCM5301X: correct rx-internal-delay-ps & enable flow control on extsw on Asus RT-AC88U

[Arınç ÜNAL]

The current rx-internal-delay-ps value on the Realtek switch node, 2000,
will be divided by 300, resulting in 6.66, which will be rounded to the
closest step value, 7. Change it to 2100 anyway to be accurate.

Commit ef136837aaf6 ("net: dsa: rtl8365mb: set RGMII RX delay in steps of
0.3 ns")

Flow control needs to be enabled on both sides. It's already enabled on the
CPU port of the Realtek switch. Enable it on the extsw port of the Broadcom
switch as well.
