Colin King has demonstrated measurable boot speed improvements (up to 3%)
by disabling many ACPI features not used by cloud kernels. That work also
allows us to unhook additional unused subsystems (Nouveau, gpiolib, pincntrl).
Disk space utilization of the kernel is reduced:
/boot by ~200KB
/lib/modules by ~170 Kb
Note that a 'Start new release' commit is also included here, since the
disabled modules need to be removed from the (proper) ABI.
