ipq806x: increase kernel partition size for the Netgear Nighthawk X4 R7500v2
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. Signed-off-by: Stefan Lippers-Hollmann <s.l-h@gmx.de>
