linux-iot2050: Disable 64K pages

Breaks at least chromium in various ways, partly because of missing
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b212921b13bda088a004328457c5c21458262fe2
in 4.19, but it also crashes later when applying that. There are also
other problems to expect for this rather exotic feature, so better drop
it.
