Now that the original SMC_USE_PXA_DMA specific code will always being
built if CONFIG_ARCH_PXA is defined, so to make this part of the code
to be PXA public, and still prevent it from being built if support of
PXA is not selected.

A SMC91X_USE_DMA flag is added to the platform data to allow platform
to choose its usage of DMA. Note this flag itself is so named to be
generic enough (assuming other platforms can also use DMA).

It keeps backward compatibility to set the SMC91X_USE_DMA flag if
SMC_USE_PXA_DMA is still defined.

Now one can use the following code

  #define SMC_IO_SHIFT	lp->io_shift

to make SMC_IO_SHIFT a variable. This, however, will slightly increase
the CPU overhead and have negative impact on the network performance.
The tradeoff is, this can be specified in the smc91x platform data so
that multiple boards support can be built in a single zImage.

And also favors the usage of SMC91X_NOWAIT over the hardcoded SMC_NOWAIT
by converting "nowait" (module parameter overridable) to platform flag.

There are several possibilities:

  1. platform data present - preferred and use as is
  2. platform data absent  - use "nowait", it can be:
       a. SMC_NOWAIT if defined
       b. default to 0 if SMC_NOWAIT isn't defined
       c. overriden by module parameter

IRQ trigger type can be specified in the IRQ resource definition by
IORESOURCE_IRQ_*, we need only one way to specify this.

This also fixes the following small issue:

To allow dynamic support for multiple platforms, when those relevant
macros are not defined for one specific platform, the default case
will be:

	- SMC_DYNAMIC_BUS_CONFIG defined
	- and SMC_IRQ_FLAGS = IRQF_TRIGGER_RISING

While if "irq_flags" is missing when defining the smc91x_platdata,
usually as follows:

  static struct smc91x_platdata xxxx_smc91x_data = {
	.flags	= SMC91X_USE_XXBIT,
  };

The lp->cfg.irq_flags will always be overriden by the above structure
(due to a memcpy), thus rendering lp->cfg.irq_flags to be "0" always.
(regardless of the default SMC_IRQ_FLAGS or IORESOURCE_IRQ_* flags)

Fixes this by forcing to use IORESOURCE_IRQ_* flags if present, and
make the only user of smc91x_platdata.irq_flags (renesas/migor) to
use IORESOURCE_IRQ_*.
