ASoC: SOF: amd: Use poll function instead to read ACP_SHA_DSP_FW_QUALIFIER
The Skyrim project and Whiterun met error when DSP loading during device boot. Ex, error in kernel log, ERR kernel: [ 16.124537] snd_sof_amd_rembrandt 0000:04:00.5: PSP validation failed. Use the snd_sof_dsp_read_poll_timeout function to successfully read the FW_QUALIFIER register Signed-off-by: Ajye Huang <ajye_huang@compal.corp-partner.google.com> Signed-off-by: V sujith kumar Reddy <Vsujithkumar.Reddy@amd.com> Link: https://lore.kernel.org/r/20221205120649.1950576-2-Vsujithkumar.Reddy@amd.com Signed-off-by: Mark Brown <broonie@kernel.org>
