ramips: fix/tidy up 4M tplink-v2-image flash layouts
For the TP-Link 4M devices with tplink-v2-image recipe
(mktplinkfw2.c), there are two different flash layouts based
on the size of the (u)boot partition:
device uboot OEM firmware OpenWrt (incl. config)
tl-wr840n-v5 0x20000 0x3c0000 0x3d0000
tl-wr841n-v14 0x10000 0x3d0000 0x3e0000
In both cases, the 0x10000 config partition is used for the firmware
partition as well due to the limited space available and since it's
recreated by the OEM firmware anyway.
However, the TFTP flashing process will only copy data up to the
size of the initial (OEM) firmware size. Therefore, while we can
use the bigger partition to have additional erase blocks on the
device, we have to limit the image sizes to the TFTP limits.
So far, only one layout definition has been set up in mktplinkfw2.c
for 4M mediatek devices. This adds a second one and assigns them
to the devices so the image sizes are correctly restrained.
