ipq40xx: add support for Meraki MR74 The Meraki MR74 is part of the "Insect" series. This device is essentially an outdoor variant of the MR33 with identical hardware, but requiring a config@3 DTS option to be set to allow booting with the stock u-boot. The install procedure is replicated from the MR33, with the exception being that the MR74 sysupgrade image must be used. Signed-off-by: Matthew Hagan
