MIPS: clean up resume declaration

This patch cleans up the declaration of the resume function by replacing
void pointers with their correct types. The irrelevant & incorrect
comment preceeding the resume function is replaced by one documenting
its function.

MIPS: replace open-coded init_dsp

There is already an init_dsp function which checks cpu_has_dsp & calls
__init_dsp if it does. Make use of it instead of duplicating the same
code.

MIPS: jz4740: update platform data for JZ4740 usb device controller

The platform data already available in tree for JZ4740 USB Device
Controller was previously used by an out-of-tree USB gadget driver
which was not relying on the musb driver and was written by Ingenic
and the Qi-Hardware community.

Update platform data for JZ4740 USB device controller to be used with
musb driver.

MIPS: malta: Incorporate PIIX4 ACPI I/O region in PCI controller resources

Boot log says:

pci 0000:00:0a.3: no compatible bridge window for [io  0x1000-0x103f]
pci 0000:00:0a.3: no compatible bridge window for [io  0x1100-0x110f]

The io resource starting point on Malta was modified by c5de50dada (MIPS:
Malta: Change start address to avoid conflicts.) to avoid conflicts with
ACPI and SMB devices. In fact, that was not needed (and now causing
southbridge ACPI missing) since 166c637075 (PCI: add pci_create_root_bus()
that accepts resource list) and 7c090e5bfa (mips/PCI: convert to
pci_scan_root_bus() for correct root bus resources) had already done the
correct fix.

This patch actually reverts the change made by c5de50dada. And with this
fix, log says:

pci 0000:00:0a.3: quirk: [io  0x1000-0x103f] claimed by PIIX4 ACPI
pci 0000:00:0a.3: quirk: [io  0x1100-0x110f] claimed by PIIX4 SMB

These things may not be used but as part of platform resources are better
off to be included.

MIPS: Netlogic: Add MSI support for XLP

Add MSI chip and MSIX chip definitions.

For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.

The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.

For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.

The MSI-X chip definition uses the standard functions to enable
and disable interrupts.
