USB: r8a66597-hcd: use platform_data instead of module_param
CPU/board specific parameters (PLL clock, vif etc...) can be set
by platform_data instead of module_param.
v2: remove irq_sense member in platform_data because it can OR in
IRQF_TRIGGER_LOW or IRQF_TRIGGER_FALLING against IORESOURCE_IRQ in
the struct resource.
