It seems that switch is no longer starting for almost ~5 minutes, but it is
working immediately. So, let's use switch to kernel 5.15 instead of
kernel 5.10.

This config is adjusted from the lighttpd config in the php7 package,
they will be installed to the same location, but the php8 and php7 packages
conflict.

Hopefully, it fixes issue reported by user on our forum:
https://forum.turris.cz/t/unprovoked-oom-mass-killing/18379/16?u=pepe

This patch was sent to OpenWrt via GitHub pull requests into the 21.02
version and in Turris Build it was included in commit
252a2443 ("patches/openwrt: 5.15:
Backport Linux modules: newer version")

This patch was only for Linux kernel 5.4, but we are using Linux kernel
5.10, so we can safely drop this.

kernel 5.15: refresh all patches")

We need FIT image support for netboot, but it is also in general quite a
handy feature.

And as well add missing Kernel option

This backports all relevant changes for Linux kernel 5.10 from OpenWrt
master branch and refreshes patches

this can cause fetch to fail on some systems because the build system
can not detect the checksum type with this trailing space

Packages related to old ISDN4Linux was dropped in Linux kernel since
version 5.3, but they were still present in OpenWrt. [1] In recent
commits, where it was updated our Linux 5.15 support the commit from
OpenWrt master branch is included, thus we need to let users know about
this breaking change, because it does not make sense to postpone it or
even have it in distribution anymore.
