platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq(). Drop irqflags member from struct usbhs_priv as this driver is used by two non DT users sh7757lcr and ecovec24 which do not pass IORESOURCE_IRQ_SHAREABLE as part of their pdata. Along this drop the IRQF_SHARED flag handling in the code.
