Adds PCI support for MPC5121

Tested with drivers/net/rtl8139.c

Support is conditional since PCI on old silicon does not work.

ads5121_PCI_config turns on PCI

In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD

Update global_data to define i2c1_clk and i2c2_clk to 85xx and 86xx.

Update the get_clocks() function in 85xx and 86xx to determine the I2C
clock frequency and store it in gd->i2c1_clk and gd->i2c2_clk.

R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

Use r2 instead.

We now use a value in the gd (global data) structure for the UART input
frequency, since the PPC4xx_SYS_INFO struct is always rewritten completely
in get_sys_info().

This patch adds support for the matrix keyboard on the lwmon5 board.
Since the implementation in the dsPCI is kind of compatible with the
"old" lwmon board, most of the code is copied from the lwmon
board directory.
