Extend mpc512x serial driver to support multiple PSC ports.
Subsequent patches for PDM360NG board support make use of this
functionality by defining CONFIG_SERIAL_MULTI in the board config
file. Additionally the used PSC devices are specified by defining
e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6.
Support for PSC devices other than 1, 3, 4 and 6 is not added
by this patch because these aren't used currently. In the future
it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and
INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c.
Additionally you have to add code for registering added
devices in serial_initialize() in common/serial.c.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

This is not only a cosmetic change as it fixes the real bug of board
reset not working with the ELDK 4.2 toolchain.

This patch removes the duplicated code for baudrate generator configuration
in the PSC serial_init() implementation by calling serial_setbrg() instead
of duplicating the code.

The wrong input frequency was used in serial_setbrg(). This patch fixes
this by using ips_clk as input frequency for the PSC baudrate generator.

This commit changes the MPC512x code to use I/O accessor calls (i.e.
out_*() and in_*()) instead of using deprecated pointer accesses.
