ar71xx: rb91x: fix pll_1000 value for eth0 to avoid packet loss
When the RB91x device uses a GbE link the connection
suffers from packet loss:
root@OpenWrt:/# ping 192.168.1.254 -s 65507 -c 20 -q
PING 192.168.1.254 (192.168.1.254): 65507 data bytes
--- 192.168.1.254 ping statistics ---
20 packets transmitted, 9 packets received, 55% packet loss
round-trip min/avg/max = 4.570/4.815/4.999 ms
Using a different PLL value fixes the issue.
