Patch from Ben Dooks
The SMDK2410 and SMDK2440 boards have a number of items
in common, including the LEDs, Ethernet, PCMCIA. Make
a common SMDK support file.

Patch from Ben Dooks
Move to using an enable count for the shared clocks
and protect the clock system using a mutex instead
of just disabling IRQs during the clock update.
Since there is little more code in the path for
non-shared clocks, the enable and disable calls
use the same code for each.

Some ARM platforms have the ability to program the interrupt controller to
detect various interrupt edges and/or levels. For some platforms, this is
critical to setup correctly, particularly those which the setting is dependent
on the device.
Currently, ARM drivers do (eg) the following:
err = request_irq(irq, ...);
set_irq_type(irq, IRQT_RISING);
However, if the interrupt has previously been programmed to be level sensitive
(for whatever reason) then this will cause an interrupt storm.
Hence, if we combine set_irq_type() with request_irq(), we can then safely set
the type prior to unmasking the interrupt. The unfortunate problem is that in
order to support this, these flags need to be visible outside of the ARM
architecture - drivers such as smc91x need these flags and they're
cross-architecture.
Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the
property that the device would like. The IRQ controller code should do its
best to select the most appropriate supported mode.

It seems that clk_use() and clk_unuse() are additional complexity
which isn't required anymore. Remove them from the clock framework
to avoid the additional confusion which they cause, and update all
ARM machine types except for OMAP.

Add generic values for the parameters to the
s3c2410_gpio_cfgpin() function, so that a caller
does not need to know the exact constant for
the specified pin.
This is very useful for the case where a driver
is passed a gpio pin number and needs to reconfigure
the pin's function.
