smc91x is shared between many different platforms. Each platform needs to specify the interrupt type, and in some cases the irq type depends on more than just the build configuration - it depends on runtime checks. Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide a way for these flags to be passed via the IRQ resource itself. Note that IRQF_TRIGGER_* constants are intentionally defined to correspond with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that the low bits of PCI iomem resources correspond with the BAR flag bits. Also provide a way to configure smc91x to read the IRQ flags from the resource. Once all platforms have been converted over (signified by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should be removed.
