tools headers: Import asm-generic MMIO helpers
Import the asm-generic MMIO helper functions from the kernel headers
into tools/include/. The top-level include is <linux/io.h> which then
includes the arch-specific <asm/io.h>, which then includes
<asm-generic/io.h>. This layout is chosen to match the kernel header
layout and to appease checkpatch.pl (which warns against including
<asm/io.h> or <asm-generic/io.h> directly).
Changes made when importing:
- Add missing includes at the top.
- Stub out mmiowb_set_pending().
- Stub out _THIS_IP_.
- Stub out log_*_mmio() calls.
- Drop the CONFIG_64BIT checks, since tools/include/linux/types.h
always defines u64.
