ipq40xx: re-enable EA6350v3, EA8300, MR8300 builds 

Raise the kernel size from 3 MB to 5 MB for EA6350v3, EA8300 and MR8300,
and correspondingly reduce the rootfs size by 2 MB:
  * modify partition definitions in related .dts files
  * modify device kernel/image sizes in generic.mk

Update to compat-version 2.0 to force factory image usage on sysupgrade,
noting the current version 1.1 is an unreleased update for DSA migration.

Also update the compat-version message, explaining the need to run one of
the following console commands to update U-Boot's kernel-size variable
before flashing the OpenWrt factory image.

    fw_setenv kernsize 500000          # (OpenWrt command line)

    setenv kernsize 500000 ; saveenv   # (U-Boot serial console)

Finally, re-enable the 3 devices.

DEVICE_COMPAT_VERSION := 2.0
DEVICE_COMPAT_MESSAGE := Kernel partition size must be increased for \
this OpenWrt version. Before continuing, you MUST issue either the \
command "fw_setenv kernsize 500000" from the OpenWrt command line, \
or "setenv kernsize 500000 ; saveenv" from the U-Boot serial console. \
Instead of the sysupgrade image, you must then install the OpenWrt \
factory image, setting the force flag and wiping the configuration. \
(e.g. "sysupgrade -n -F openwrt-squashfs-factory.bin" on command line)
