Default config file for mpc8272ads (powerpc port).Though relevant bits went
in, it is required to keep proper default configuration for the target,
which seems to be missed initially.

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the
current kernel. Current patch fixes it, as well as other inconsistencies
expressed, that do not permit targets from working properly:
- Updated dts with a chosen node with interrupt controller,
- fixed messed device IDs among CPM2 SoC devices,
- corrected odd header name and fixed type in defines,
- Added 82xx subdir to the powerpc/platforms Makefile, missed during
initial commit,
- new solely-powerpc header file for 8260 family (was using one from
arch/ppc, this one cleaned up from the extra stuff), in fact for now
a placeholder to get the board-specific includes for stuff not yet
capable to live with devicetree peeks only
- Fixed couple of misprints in reference mpc8272 dts.

This contains important fixes for the CPM2 PIC code. Eliminated
CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt
mapping. Updated devicetree files to reflect that. Changed direct
IC-related IO accesses to the IO accessors. Fixed all the sense values to
keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs
and hence could be hardly usable.

Add the inline function "is_power_of_2()" to log2.h, where the value
zero is *not* considered to be a power of two.

Allow more than the default 256 MPIC sources. Allocates a new flag
(MPIC_LARGE_VECTORS) to be used by platform code when instantiating
the mpic.
I picked 11 bits worth right now since it would cover the number of
sources on any hardware I have seen. It can always be increased later
if needed.

Support for PA6T-style PMC registers.
PMCs are completely implementation-dependent on PPC, and PA6T numbers them
differently from the IBM model.

Introduce _SYSDEV_ATTR(), to be used to just define the struct, and not a
named variable with the attribute. Useful for arrays of sysdev_attributes.

Add cputable entries for which type of PMC implementation the processor
has.
I've only filled in the current 64-bit processors, the unfilled default
value will have same behaviour as before so it can be done over time
as needed.
Also tidy up the dummy_perf implementation a bit, aggregating it into
one function with ifdefs instead of several.

Clean up the ctr_read/write a bit. It's currently defined in the
include but only used in one C file each. The only exception is the
classic version, so keep that in the include and define in the C file
as appropriate.

The grow() function in the rheap library allocates a larger array of blocks,
copies the contents of the old blocks array to the newly allocated array and
fixes the list_head pointers after the copy. At the end, the new blocks must
be enqueued to the empty_list of the rh_info_t structure. This patch fixes
a bug where the code was indexing past the end of the array when enqueueing
blocks. The UCC ethernet driver, which uses the rheap allocator, experiences
kernel panics because of this bug.
