ALSA: hda/intel: Make MSI address limit based on the device DMA limit
The hda/intel driver restricts the MSI message address for devices which do
not advertise full 64-bit DMA address space support to 32-bit due to the
former restrictions of the PCI/MSI code which only allowed either 32-bit or
a full 64-bit address range.
This does not work on platforms which have a MSI doorbell address above the
32-bit boundary but do not support the full 64 bit address range.
The PCI/MSI core converted this binary decision to a DMA_BIT_MASK() based
decision, which allows to describe the device limitations precisely.
Convert the driver to provide the exact DMA address limitations to the
PCI/MSI core. That allows devices which do not support the full 64-bit
address space to work on platforms which have a MSI doorbell address above
the 32-bit limit as long as it is within the hardware's addressable range.
