Subject: [PATCH] fastboot: convert a few non-critical ACPI drivers to async initcalls
This patch converts a few non-critical ACPI drivers to async initcalls;
these initcalls (battery, button and thermal) tend to take quite a bit of
time (100's of milliseconds) due to the hardware they need to talk to,
but are otherwise clearly non-essential for the boot process.
