Whitespace fixes for files in sys/mips/nlm

Clean up whitespace issues under sys/mips/nlm (except dev). No
functional change in this commit.

Improve additional interrupt ACK for Broadcom XLP

Handling some interrupts in XLP (like PCIe and SATA) involves writing to
vendor specific registers as part of interrupt acknowledgement.

This was earlier done with xlp_establish_intr(), but a better solution
is to provide a function xlp_set_bus_ack() that can be used with
cpu_establish_hardintr(). This will allow platform initialization code to
setup these ACKs without changing the standrard drivers.

Remove run-time allocation of XLP IRQs

Follow the same static IRQ to Interrupt Table Entry mapping as the other
OS supported on XLP.

Add netlogic,xlp-pic as interrupt controller for XLP

Add an empty driver for netlogic,xlp-pic to ensure that the device tree
is correct and has an interrupt controller.

Update memory and resource allocation code for SoC devices

The XLP on-chip devices have PCI configuration headers, but some of the
devices need custom resource allocation code.
- devices with no MEM/IO BARs with registers in PCIe extended reg
space have to be handled in memory resource allocation
- devices without INTPIN/INTLINE in PCI header can be supported
by having these faked with a shadow register.
- Some devices does not allow 8/16 bit access to the register space,
he default bus space cannot be used for these.

Subclass pci and override attach and resource allocation methods to
take care of this.

Remove earlier code which did this partially.

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.

Add MIPS platform files for Netlogic XLP SoC.

Processor, UART, PIC and Messaging Network code. Also add
sys/mips/nlm/hal for on-chip device registers.
