This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.

Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.

This patch fixes the preempt leak in the cpuidle path invoked from
cpu-hotplug. The fix is suggested by Russell King and is based
on x86 idea of calling init_idle() on the idle task when it's
re-used which also resets the preempt count amongst other things

According to the header file, dt3155_io.h, the 50/60 Hz configuration
is controlled by a bit in the I2C CSR2 register (bit 2).  The function
dt3155_init_isr actually reads the I2C CONFIG register into the global
I2C_CSR union variable then modifies the bit.  It then does a write
to the I2C CONFIG register with the global I2C_CONFIG union variable
which is not even set with a value anywhere in the driver.

My guess is 50Hz operation doesn't even work as-is.

Fix this by actually reading and writing the correct register with
the correct value.

When detaching a port from the client side (usbip --detach 0),
the event thread, on the server side, is going to deadlock.
The "eh" server thread is getting USBIP_EH_RESET event and calls:
  -> stub_device_reset() -> usb_reset_device()
the USB framework is then calling back _in the same "eh" thread_ :
  -> stub_disconnect() -> usbip_stop_eh() -> wait_for_completion()
the "eh" thread is being asleep forever, waiting for its own completion.
This patch checks if "eh" is the current thread, in usbip_stop_eh().

With patch as1329 (USB: convert to the runtime PM framework),
we make USB_SUSPEND depend on PM_RUNTIME instead of CONFIG_PM.

Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND.

If PM_RUNTIME is not enabled, and we try to enable USB_OTG,
we will end up with CONFIG_USB_SUSPEND selected. This is
due to a known bug with the select statement.

This makes the build break on various OMAP configs (which
have CONFIG_USB_OTG set by default, but do not yet have
CONFIG_PM_RUNTIME enabled).

Avoid this by changing the logic for CONFIG_USB_OTG from
"select USB_SUSPEND" to "depends on USB_SUSPEND"
