+ * TAS2563 Post-Firmware ASI Configuration.
+ *
+ * The DSP firmware loading can overwrite the ASI (Audio Serial Interface)
+ * registers that configure the I2S/TDM audio path to the amplifier.
+ * This function re-applies the correct ASI configuration after firmware load,
+ * matching the reference initialization sequence used by the vendor script:
+ *   - Software reset
+ *   - ASI_CFG  = 0x09 (I2S mode, master/slave config)
+ *   - ASI_SR   = 0x02 (sample rate divider for 48 kHz)
+ *   - ASI_DA   = 0xf1 (data alignment / slot assignment)
+ *   - ASI_TDM  = 0x02 (TDM mode select)
+ *   - ASI_DL   = 0x00 (delay line off)
+ *   - ASI_SLOT = 0x99 (slot enable mask for 2-channel stereo)
+ *   - CHNL_0   = 0x02 (channel mapping)
+ *   - ASI_FS   = 0x1e or 0x2e (frame sync, device-specific: bit4 selects
+ *                which of the two devices is the "primary" for FS generation)
+ *   - ASI_APPLY= 0x00 (trigger configuration update)
