Increase the available flash memory size in Netgear R7800
by repurposing the unused "netgear" partition that is
located after the firmware partition.
Available flash space for kernel+rootfs+overlay increases
by 68 MB from 32 MB to 100 MB.
In a typical build, overlay space increases from 15 to 85,
increasing the package installation possibilities greatly.
Reverting to the OEM firmware is still possible, as the OEM
firmware contains logic to initialise the "netgear" partition
if its contents do not match expectations. In OEM firmware,
"netgear" contains 6 UBI sub-partitions that are defined in
/etc/netgear.cfg and initialisation is done by /etc/preinit

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

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.)

This commit moves the device profiles within the ipq806x/generic
subtarget into their own includable .mk file, to support eventually
having subtargets other than generic.
