Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the
2 MB reserved for the kernel partition by the OEM firmware anymore.
This patch increases the kernel partition from 2 MB to 4 MB, at the
expense of the rootfs, for all supported kernels.
WARNING: This breaks sysupgrade! Flashing a firmware containing this
changed partitioning from an older image with 2 MB reserved for the
kernel partion requires the tftp recovery procedure, thereby losing
all settings.
This change follows the functional example of the Netgear r7800, but
has not been runtime tested on a Netgear Nighthawk X4 D7800.

The default image does not fit 2 MB anymore, expand kernel partition
to 3 MB.
Upgrading should work transparently via sysupgrade in both directions.
Another option would be to merge "kernel" and "rootfs" into a single
"firmware" partition using MTD_SPLIT_TPLINK_FW, but just changing the
sizes of the existing partitioning has been deemed safer in the absence
of an actual runtime test on an affected device; the maximum for rootfs
changes from 10.4 MB to 9.4 MB.
This change follows the example for the TP-Link Archer C2600, but has
not been runtime tested on a TP-Link Archer VR2600v.

- Rebased the patches for 4.14
- Dropped spi-qup and 0027, 0028, 0029
clk patches since it's already included
in upstream.
Tested on IPQ AP148 Board:
1) NOR boot and NAND boot
2) Tested USB and PCIe interfaces
3) WDOG test
4) cpu frequency scaling
5) ethernet, 2G and 5G WiFi
6) ubi sysupgrade
