ASoC: SOF: Intel: MTL: Reduce the DSP init timeout

Browse Source 
[ Upstream commit e0f96246c4402514acda040be19ee24c1619e01a ]

20s seems unnecessarily large for the DSP init timeout. This coupled with
multiple FW boot attempts causes an excessive delay in the error path when
booting in recovery mode. Reduce it to 0.5s and use the existing
HDA_DSP_INIT_TIMEOUT_US.
