cb5902d603 atheros: convert AR2315 GPIO code to platform driver
Convert gpiolib realization to platform driver and move to the
appropriate subdirectory. Misc GPIO interrupt acknowledgement placed
to the MISC IRQ handler since in fact we can detect only one GPIO state
change.

0e86c116cb atheros: rework chained interrupts handling
Call generic_handle_irq() instead of do_IRQ() for chained interrupts,
remove XXX_NONE interrupts and call spurious_interrupt() when an interrupt
is unexpected.

413736e5f8 atheros: add AR2316 and AR2318 SoCs detection
Tested with AR2315, AR2316 and AR2317 SoCs, not tested with AR2318 but
changes seems correct: revision is one more than AR2317.

94efeaa51f atheros: ar2315-pci: update host bridge resources
It seems that the PCI controller does not support I/O ports, so remove
the ports range. Also correct the beginning of the memory range and its
size.

78c914ffe5 atheros: ar2315-pci: rework the configuration access code
Use __raw_{read,write}l accessors and use Abort interrupt to detect a
configuration space read/write errors. The second change improves errors
detection, what improves the device presence detection and helps us to
avoid following (and similar) errors:

pci 0000:00:00.2: ignoring class 0x7e0200 (doesn't match header type 02)
pci 0000:00:00.2: bridge configuration invalid ([bus 03-90]), reconfiguring
pci 0000:00:00.2: not setting up bridge for bus 0000:01

dbdd8906ac atheros: ar2315-pci: rework interrupt handling
Add PCI IRQ controller to facilitate interrupt handling, move interrupts
initialization to the IRQ controller initialization from
pcibios_plat_dev_init() callback.

Also remove odd PCI dev configuration manipulation from pcibios_plat_dev_init()
callback.

0f645cbd83 atheros: ar2315-pci: rework host controller initialization
Explicitly configure PCI host controller, and do not expose it to PCI
subsystem. The PCI host controller acts as a usual PCI device connected
to the bus, but its configuration as a usual PCI device is senseless,
since the host controller provide access to _internal_ memory space for
_external_ device.
