shdma-arm.h was introduced with commit 1e69653d40f1 ("DMA: shdma: add
r8a73a4 DMAC data to the device ID table"), and its sole user was
removed with commit a19788612f51 ("dmaengine: sh: Remove R-Mobile APE6
support"). The latter mentions r8a73a4.dtsi but shdma support was
removed from that with commit cfda82037780 ("ARM: dts: r8a73a4: Remove
non-functional DMA support"), so it seems this is safe to remove.

All shdma DMACs on ARM SoCs share certain register layout patterns, which
are currently defined in arch/arm/mach-shmobile/include/mach/dma-register.h.
That header is included by SoC-specific setup-*.c files to be used in DMAC
platform data. That header, however, cannot be directly used by the driver.
This patch copies those defines into a driver-local header to be used by
Device Tree configurations.
