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 R7500v2.

- Rebased the patches for 4.14
- Dropped spi-qup and 0027, 0028, 0029
clk patches since it's already included
in upstream.

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
