dmaengine: sirf: use __maybe_unused to hide pm functions

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.
