[NET] smc91x: remove "irq_flags" from "struct smc91x_platdata"
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_*.
