irq_of_parse_and_map() returns 0 on error, no NO_IRQ, so the
failure condition can never be met.

This changes the comparison to check for zero instead.

This is in preperation of moving to a callback that provides results to the
callback for the transaction. The conversion will maintain current behavior
and the driver must convert to new callback mechanism at a later time in
order to receive results.

a dump_stack(). So remove the site specific error messages.

The sirfsoc_dmadata structs are not used outside the driver, so
remove build warnings by making them static. Fixes:

drivers/dma/sirf-dma.c:1129:24: warning: symbol 'sirfsoc_dmadata_a6' was not declared. Should it be static?

The sirf dma driver uses #ifdef to check for CONFIG_PM_SLEEP
for its suspend/resume code but then has no #ifdef for the
respective runtime PM code, so we get a warning if CONFIG_PM
is disabled altogether:

drivers/dma/sirf-dma.c:1000:12: error: 'sirfsoc_dma_runtime_resume' defined but not used [-Werror=unused-function]

This removes the existing #ifdef and instead uses __maybe_unused
annotations for all four functions to let the compiler know it
can silently drop the function definition.

If DMA interrupt comes and is latched by IRQ controller during the
execution of dma_terminate_all(), dma_irq routine will be executed
after dma terminated, and it will cause kernel panic.
We clear DMA interrupts in dma_terminate_all() to avoid this useless
interrupt.
