[PATCH v4 1/6] dmaengine: shdma: add IRQ resource name definition macros

["Shimoda, Yoshihiro" <yoshihiro.shimoda.uh@renesas.com>]

The SH DMAC has an ERROR IRQ and channel IRQs. So, the defination
macros are used as the resource name, and the resource name will be
used to detect each IRQ by the driver.
