Sughosh Ganu bd3f9ee679 kbuild: Bump the build system to 6.1 
Our last sync with the kernel was 5.1.

We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.

This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.

# A note on target vs host configuration:
#
# Host tools can be used across multiple targets, or different configurations
# of the same target. Thus, host tools must be able to handle any combination
# of target configurations. To prevent having different variations of the same
# tool, the tool build options may not depend on target configuration.
#
# Some linux distributions package these utilities as u-boot-tools, and it
# would be unmaintainable to have a different tool variation for each
# arch or configuration.
#
# A couple of simple rules:
#
# 1) Do not use target CONFIG_* options to enable or disable features in host
# tools. Only use the configs from tools/Kconfig
# 2) It's okay to use target configs to disable building specific tools.
# That's as long as the features of those tools aren't modified.
#
# Enable all the config-independent tools
