Currently there are a number of platforms that open code access to
the ppc_pci_flags global variable.  However, that variable is not
present if CONFIG_PCI is not set, which can lead to a build break.

This introduces a number of accessor functions that are defined
to be empty in the case of CONFIG_PCI being disabled.  The
various platform files in the kernel are updated to use these.

The Arches Evaluation board is based on the AMCC 460GT SoC chip.
This board is a dual processor board with each processor providing
independent resources for Rapid IO, Gigabit Ethernet, and serial
communications.  Each 460GT has it's own 512MB DDR2 memory, 32MB NOR FLASH,
UART, EEPROM and temperature sensor, along with a shared debug port.
The two 460GT's will communicate with each other via shared memory,
Gigabit Ethernet and x1 PCI-Express.

Add explicit support for the AMCC Glacier eval board to Kconfig and the
ppc44x_simple file.  Also removes the cayonlands compatible entry from the
DTS file.

This adds a common board file for almost all of the "simple" PowerPC 44x
boards that exist today.  This is intended to be a single place to add
support for boards that do not differ in platform support from most of the
evaluation boards that are used as reference platforms.  Boards that have
specific requirements or custom hardware setup should still have their own
board.c file.
