[PATCH v11] ALSA: hda/tas2781: Add tas2781 hda SPI driver

27 Jul 2024

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda.
It use ACPI node descript about parameters of TAS2781 on SPI, it like:
    Scope (_SB.PC00.SPI0)
    {
        Device (GSPK)
        {
            Name (_HID, "TXNW2781")  // _HID: Hardware ID
            Method (_CRS, 0, NotSerialized)
            {
                Name (RBUF, ResourceTemplate ()
                {
                    SpiSerialBusV2 (...)
                    SpiSerialBusV2 (...)
                }
            }
        }
    }
And in platform/x86/serial-multi-instantiate.c, those spi devices will be
added into system as a single SPI device, so TAS2781 SPI driver will
probe twice for every single SPI device. And driver will also parser
mono DSP firmware binary and RCA binary for itself.
The code support Realtek as the primary codec.
In patch version-10, add multi devices firmware binary support,
to compatble with windows driver, they can share same firmware binary.
