1374e5a721 ar71xx: rb91x: fix ethernet packet loss issues
The RB91x boards are suffering from ethernet packet loss after a cold
boot. The cause of the problem is that the AR8035 PHYs requires special
register settings to work reliably on these boards.

Enable the RGMII TX, RX delays and disable SmartEE functionality of
the AR8035 PHYs. Also enable the RXD delay in the ETH_CFG register
to fix the issue.

14d95026b2 ar71xx: rb91x: add SPI device for the serial shift register
The RB91x boards are using a serial shift register
connected to the SPI bus to drive some of the LEDs.

Rework the board setup code to register a SPI device
for that. This makes it possible to use the 'spi-74x164'
driver to control the device.

4e0309630b 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.
