ASoC: bcm: bcm63xx-pcm-whistler: Check return value of of_dma_configure()

Browse Source 
[ Upstream commit 0ebbd45c33d0049ebf5a22c1434567f0c420b333 ]

bcm63xx_soc_pcm_new() does not check the return value of
of_dma_configure(), which may fail with -EPROBE_DEFER or
other errors, allowing PCM setup to continue with incomplete
DMA configuration.

Add error checking for of_dma_configure() and return on failure.

Fixes: 88eb404ccc ("ASoC: brcm: Add DSL/PON SoC audio driver")
