virt_to_abs() is just a wrapper around __pa(), use __pa() directly.

We should be including <asm/page.h> to get __pa(). abs_addr.h will be
removed shortly so drop that.

We were getting of.h via abs_addr.h so we need to include that directly.

Having done all that, clean up the ordering of the includes.

This patch adds the driver for interacting with the 842
compression accelerator on IBM Power7+ systems.

The device is a child of the Platform Facilities Option (PFO)
and shows up as a child of the IBM VIO bus.

The compression/decompression API takes the same arguments
as existing compression methods like lzo and deflate.  The 842
hardware operates on 4K hardware pages and the driver breaks up
input on 4K boundaries to submit it to the hardware accelerator.
