Update the L1D cache flush sequence when enabling threads.

Added more comments to the code.

Do dcache flush on CPU core before enabling threads.

The dcache flush has to be done using the core control registers before
splitting the L1D cache by enabling the hardware threads.

Also replace .word calls for mfcr/mtcr with a C macro.

MIPS XLP platform code update.

* Update the hardware access register definitions and functions to bring
them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
>32 cpus.
