usb: renesas_usbhs: add IRQ resource decoding for IRQF_SHARED
In case of the SH7757, the irq number of USB module and SUDMAC are the same. So, we have to set the IRQF_SHARED in such a case. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
