[PULL,linux-aws] Disable many ACPI features, Nouveau, gpiolib, pinctrl

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.
