ipq806x: convert TP-Link Archer VR2600v to denx,uimage

Browse Source 
The recent device-tree modification that added pre-cal
nvmem-cells pushed the device's kernel+dtb over the
allotted 3072k KERNEL_SIZE.

> WARNING: Image file tplink_vr2600v-uImage is too big: 3147214 > 3145728

There was a previous kernel partition size upgrade:
commit 0c967d92b3 ("ipq806x: increase kernel partition size for the TP-Link Archer VR2600v")
It has been seemingly upgraded from a 2048k KERNEL_SIZE in the past.
The commit talks about using the MTD_SPLIT_TPLINK_FW. But looking at
the image make recipe, there is no code that adds a TPLINK header.
So instead the board will use "denx,umimage". This requires
MTD_SPLIT_UIMAGE_FW, but this is present thanks to some NEC devices.

(Maybe the MTD_CONFIG_ARGS can be removed as well? But it could be
there because of the padding at the beginning. This needs testing.)
