Make ubiquiti-rocket-m a separate device rather than a bullet-m alias to
enable USB support and allow adding devive-specific packages.

This commit adds support for the AVM Fritz!Box 4020 WiFi-router.

SoC:   Qualcomm Atheros QCA9561 (Dragonfly) 750MHz
RAM:   Winbond W971GG6KB-25
FLASH: Macronix MX25L12835F
WiFi:  QCA9561 b/g/n 3x3 450Mbit/s
USB:   1x USB 2.0
IN:    WPS button, WiFi button
OUT:   Power LED green, Internet LED green, WLAN LED green,
       LAN LED green, INFO LED green, INFO LED red
UART:  Header Next to Black metal shield
       Pinout is 3.3V - RX - TX - GND (Square Pad is 3.3V)
       The Serial setting is 115200-8-N-1.

Tested and working:
 - Ethernet (LAN + WAN)
 - WiFi (correct MAC)
 - Installation via EVA bootloader
 - OpenWRT sysupgrade
 - Buttons
 - LEDs

Not working:
 - USB port

Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1). Firmware can be uploaded
like following:

  ftp> quote USER adam2
  ftp> quote PASS adam2
  ftp> binary
  ftp> debug
  ftp> passive
  ftp> quote MEDIA FLSH
  ftp> put openwrt-sysupgrade.bin mtd1

Note that this procedure might take up to two minutes. After transfer is
complete you need to powercycle the device to boot OpenWRT.

Let's keep the default package selection to hardware support.

ar71xx-generic and -tiny benefit most from the optimized kernel, as they
contain all devices with 32MB RAM. We enable CONFIG_GLUON_SPECIALIZE_KERNEL
for all targets using the mips24_kc architecture so packages shared between
targets don't need to be rebuild all the time.

kmod-usbip is broken since the last kernel update.

adding an alias as it uses the same image as the TL-WR940N v4

including backport of mtd patches.

The general flash issue (32MB) was discussed here:

The resulting patch was the following:

Another patch by nbd168 added the required mtd read operations for supporting ZBT-WG3526-32M:

There is no wifi, so there is no bad wifi.

[Matthias Schiffer: rebase onto master]

[Matthias Schiffer: remove patch "ramips: simplify ubnt-erx-sfp device
definition", as it depends on other patches that have not been backported]

BROKEN because of stability issues with 5GHz enabled.

As the default package list is now handled using the 'packages' directive,
explicit wpad-mini removals in target definitions can be dropped.

This, together with a new try_config directive, will allow checking the
generic config and make it more flexible.
