Subject: [PATCH 1/2] ASoC: SOF: amd: move iram-dram fence register programming sequence
As per design, ACP iram-dram fence register sequence should be initiated
before triggering SHA dma. This ensures that IRAM size will programmed
correctly before initiaing SHA dma.
Fixes: 094d11768f74 ("ASoC: SOF: amd: Skip IRAM/DRAM size modification for Steam Deck OLED")
