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.
