Subject: ppc/85xx: Add a structure defn for PIXIS registers

The various boards that have PIXIS FPGAs have slightly different
register definitions, however there is some common functionality (like
reset, ICS307 clk control, etc) that can be shared.

The struct definition exists for MPC8536DS, MPC8544DS, MPC8572DS,
MPC8610HPCD, and MPC8641HPCN boards.

Also fixed ngpixis to be __packed__ instead of aligned.

Subject: Move ICS CLK chip frequency calculation code into a common board
 library

We have several boards that use the same ICS307 CLK chip to drive the
System clock and DDR clock.  Move the code into a common location so we
share it.

Convert the P2020DS board as the first to use the new common ICS307
code.

Subject: 83xx/85xx/86xx: LBC register cleanup

Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers.  Merge
this into a single spot.

To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.

In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.

I have done a successful ppc build all and tested a board or two from
each processor family.

Subject: powerpc: add support for the Freescale P1022DS reference board

Specifics:

1) 36-bit only
2) Booting from NOR flash only
3) Environment stored in NOR flash only
4) No SPI support
5) No DIU support

Subject: powerpc/85xx: Move p1022ds slot code into board file

The code to map SERDES configs to slot names is board specific and not
chip specific.  Thus it should live in board/freescale/p1022ds/ and not
in arch/powerpc/cpu/.
