ASoC: SOF: amd: acp-loader: Use GFP_KERNEL for DMA allocations in resume context

Browse Source 
commit eb3bb14528 upstream.

Replace GFP_ATOMIC with GFP_KERNEL for dma_alloc_coherent() calls. This
change improves memory allocation reliability during firmware loading,
particularly during system resume when memory pressure is high. Because
of using GFP_KERNEL, reclaim can happen which can reduce the probability
of failure.

Fixes memory allocation failures observed during system resume with
fragmented memory conditions.

	snd_sof_amd_vangogh 0000:04:00.5: error: failed to load DSP firmware after resume -12

Fixes: 145d7e5ae8 ("ASoC: SOF: amd: add option to use sram for data bin loading")
Fixes: 7e51a9e38a ("ASoC: SOF: amd: Add fw loader and renoir dsp ops to load firmware")
