[POWERPC] bestcomm: Restrict bus prefetch bugfix to original mpc5200 silicon.
Only the MPC5200 needs this bug fix. MPC5200B is okay.

[POWERPC] bestcomm: GenBD task support
This is the microcode for the GenBD task and the associated
support code. This is a generic task that copy data to/from
a hardware FIFO. This is currently locked to 32bits wide
access but could be extended as needed.
The microcode itself comes directly from the offical
API (v2.2)

[POWERPC] bestcomm: core bestcomm support for Freescale MPC5200
This patch adds support for the core of the BestComm API
for the Freescale MPC5200(b). The BestComm engine is a
microcode-controlled / tasks-based DMA used by several
of the onchip devices.
Setting up the tasks / memory allocation and all common
low level functions are handled by this patch.
The specifics details of each tasks and their microcode
are split-out in separate patches.
This is not the official API, but a much cleaner one.
(hopefully)
