The current code uses static resources and static platform
device instances for the possible USB controllers in the
system. These static variables contains initial values which
leads to data segment pollution.
Remove the static variables and use dynamically allocated
structures instead.

Use the ATH79_MISC_IRQ() macro instead.

Remove the individual ATH79_CPU_IRQ_* constants and
use the new macro instead of those.

This patch (as1623) removes the ehci_port_power() routine and all the
places that call it. There's no reason for ehci-hcd to change the
port power settings; the hub driver takes care of all that stuff.
There is one exception: When the controller is resumed from
hibernation or following a loss of power, the ports that are supposed
to be handed over to a companion controller must be powered on first.
Otherwise the handover won't work. This process is not visible to the
hub driver, so it has to be handled in ehci-hcd.

This improves code readability, and ensures that
all resource fields will be initialized correctly.
Additionally, it helps to reduce the size of the
kernel image by using uninitialized resource
variables.

The currently assigned IRQ number to the OHCI controller is incorrect for
the AR7240 SoC, and that leads to the following error message from the
OHCI driver:
ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
ath79-ohci ath79-ohci: Atheros built-in OHCI controller
ath79-ohci ath79-ohci: new USB bus registered, assigned bus number 1
ath79-ohci ath79-ohci: irq 14, io mem 0x1b000000
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 1 port detected
usb 1-1: new full-speed USB device number 2 using ath79-ohci
ath79-ohci ath79-ohci: Unlink after no-IRQ? Controller is probably using the wrong IRQ.
Fix this by using the correct IRQ number.

The ath79 usb driver doesn't do anything special and is now converted
to the generic ehci and ohci driver.
This was tested on a TP-Link TL-WR1043ND (AR9132)

Also select the USB_ARCH_HAS_EHCI symbol in order to make the
EHCI driver available.

Add common platform_device and helper code to make the registration of
the built-in USB controllers easier on the board which are using them.
Also register the USB controller on the AP81 and PB44 boards.
