MLK-20095-4: ASoC: fsl: Use hardwired system address offset source select for QM
We set system address offset select to 0 on QM because of the following reasons:
* SC_C_OFS_PERIPH, it is not available for QM
* SC_C_OFS_AUDIO, it is not used
* SC_C_OFS_IRQ, needs to get outside of the VPU.
A simplified version of the code is:
if (dsp_priv->dsp_board_type == DSP_IMX8QXP_TYPE) {
sc_misc_set_control(ipcHndl, SC_R_DSP, SC_C_OFS_SEL, 1);
sc_misc_set_control(ipcHndl, SC_R_DSP, SC_C_OFS_PERIPH, 0x5A);
sc_misc_set_control(ipcHndl, SC_R_DSP, SC_C_OFS_IRQ, 0x51);
sc_misc_set_control(ipcHndl, SC_R_DSP, SC_C_OFS_AUDIO, 0x80);
}
} else {
sc_misc_set_control(ipcHndl, SC_R_DSP, SC_C_OFS_SEL, 0);
}
