ramips:  add  support  for  Linksys  EA7300  v2

This submission relied heavily on the work of
Santiago Rodriguez-Papa <contact@rodsan.dev>

Specifications:

*  SoC:            MediaTek  MT7621A                            (880  MHz  2c/4t)
*  RAM:            Nanya  NT5CC128M16IP-DIT              (256M  DDR3-1600)
*  Flash:        Macronix  MX30LF1G18AC-TI            (128M  NAND)
*  Eth:            MediaTek  MT7621A                            (10/100/1000  Mbps  x5)
*  Radio:        MT7603E/MT7615N                                       (2.4  GHz  &  5  GHz)
                         4  antennae:  1  internal  and  3  non-deatachable
*  USB:            3.0  (x1)
*  LEDs:
         White      (x1  logo)
         Green      (x6  eth  +  wps)
         Orange    (x5,  hardware-bound)
*  Buttons:
         Reset      (x1)
         WPS          (x1)

Installation:

Flash  factory  image  through  GUI.

This  might  fail  due  to  the  A/B  nature  of  this  device.  When  flashing,  OEM
firmware  writes  over  the  non-booted  partition.  If  booted  from  'A',
flashing  over  'B'  won't  work.  To  get  around  this,  you  should  flash  the
OEM  image  over  itself.  This  will  then  boot  the  router  from  'B'  and
allow  you  to  flash  OpenWRT  without  problems.

Reverting  to  factory  firmware:

Hard-reset  the  router  three  times  to  force  it  to  boot  from  'B.'  This  is
where  the  stock  firmware  resides.  To  remove  any  traces  of  OpenWRT  from
your  router  simply  flash  the  OEM  image  at  this  point.
