Older pSeries systems with serial ports dont get any console output after
recent changes. CONFIG_ISA does not make sense for CONFIG_PPC_PSERIES
because it enables lots of old drivers. Instead, remove the dependency on
CONFIG_ISA from the serial port discovery code.

Only build in support for ISA and PCI cases if we have enabled CONFIG_ISA
and CONFIG_PCI. Additionally, isa_bridge is a global so we shouldn't use
it a parameter name since it gets redefined to NULL when !CONFIG_PCI.

Add the ability to configure and initialize legacy 8250 serials
ports on an SOC bus. Also, fixed an issue that we would not
configure any serial ports if "linux,stdout-path" was not found.

This updates the OF address parsers to return the IO flags
indicating the type of address obtained. It also adds a PCI
call for converting physical addresses that hit IO space into
into IO tokens, and add routines that return the translated
addresses into struct resource

This fixes the new serial probe code with some PCI MMIO UARTs, and fixes
CHRP build with ARCH=powerpc.

This makes it deal with the fact that the Pegasos firmware reports that
its clock frequency is zero...

This moves the discovery of legacy serial ports to a separate file,
makes it common to ppc32 and ppc64, and reworks it to use the new OF
address translators to get to the ports early. This new version can also
detect some PCI serial cards using legacy chips and will probably match
those discovered port with the default console choice.
Only ppc64 gets udbg still yet, unifying udbg isn't finished yet.
It also adds some speed-probing code to udbg so that the default console
can come up at the same speed it was set to by the firmware.
