mpc85xx: add support for Aerohive BR200-WP

The following adds the Aerohive BR200-WP router to OpenWrt under
the mpc85xx/p1010 subtarget.

Hardware:
- SoC: Freescale P1011
- NOR: Intel JS28F512M29EWH 64MB
- Memory: 2x Nanya NT5TU64M16GG-AC 128MB (Total of 256MB)
- 2.4GHz WiFi: Atheros AR9390-AL1A
- Eth1: Atheros AR8035-A PoE
- 2x LEDs
- 1x Button
- PoE PSE

Flashing:
1. Hook into UART (9600 baud) and enter U-Boot. You may need to enter a
password of administrator or AhNf?d@ta06 if prompted.
2. Once in U-Boot, tftp boot the initramfs image:
   dhcp; setenv serverip 192.168.1.3;
   tftpboot 0x2004000 openwrt-mpc85xx-p1010-aerohive_br200-wp-initramfs-kernel.bin;
   bootm 0x2004000;
3. Once booted, scp over the sysupgrade file and sysupgrade the device
to flash LEDE to the NOR.

Note:

MAC assigns are taken from stock firmware:

Wifi0.1  08ea:44XX:XXd4 access         D     1(20MHz)     -  radio_ng0   hive0        -

Note2:
PoE PSE could be managed with `realtek-poe` package. Example port
config:

config port
        option enable   '1'
        option id       '4'
        option name     'lan2'
        option poe_plus '0'
        option priority '2'
config port
        option enable   '1'
        option id       '3'
        option name     'lan1'
        option poe_plus '0'
        option priority '1'

(switch@0 -> switch@10, Device's quickstart says LEDs are
amber and white => add function+color properties but keep
labels around, use pr_info)
