dmaengine: sh: rz-dmac: Move interrupt request after everything is set up

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: sh: rz-dmac: Move interrupt request after everything is set up

Once the interrupt is requested, the interrupt handler may run immediately.
Since the IRQ handler can access channel->ch_base, which is initialized
only after requesting the IRQ, this may lead to invalid memory access.
Likewise, the IRQ thread may access uninitialized data (the ld_free,
ld_queue, and ld_active lists), which may also lead to issues.

Request the interrupts only after everything is set up. To keep the error
path simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().
