[PATCH 4/7] ASoC: amd: acp: acp63: Use AMD_NODE

[Mario Limonciello <superm1@kernel.org>]

From: Mario Limonciello <mario.limonciello@amd.com>

All consumers of SMN in the kernel should be doing it through the
functions provided by AMD_NODE.

Stop using the local SMN read/write symbols and switch to the AMD_NODE
provided ones.

Tested by: Venkata Prasad Potturu <venkataprasad.potturu@amd.com>
