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.

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.

("patches/openwrt: gcc 8.4.0: mpc85xx SPE: expect '-sf' `ld` suffix even
with SPE enabled")

This was allowed because in OpenWrt 21.02 branch, there is now included
this commit [1].

This enables MLGRU for Linux 5.15

Difference in power consumption between ondemand and performance
governors is negligible (at least on our boards) while ondemand has
noticeable lag when starting transmissions. Performance was also default
governor in previously shipped kernel, so let's stick to it.

We decided that we are not going to release Turris OS 6.0.2 RC2 with
more changes as we would like to release at least something this week to
improve the current behavior of Rainbow, etc.

So, changes added into RC2 are moved to Turris OS 6.0.3

This patch is required only for the latest Linux backports, but we are
not using it, so we can drop it. Reference:
685634ce ("patches/openwrt: 5.15:
mac80211: downgrade")

This reverts commit 838a2844.

Unfortunately, the latest Linux backports does not work for us as there
are some issues in ath10k and mt76, thus Wi-Fi is not working as we
would like.
