soc/intel/mtl/acpi: add FSPI to DSDT
Getting an error from the Kernel on Rex devices:
> ACPI Error: AE_NOT_FOUND, While resolving a named reference
> package element - \_SB_.PCI0.FSPI (20210730/dspkginit-438)
FSPI is defined in src/soc/intel/meteorlake/chipset.cb:
device pci 1f.5 alias fast_spi on end
This CL adds the corresponding FSPI device to the DSDT to prevent
the error mentioned above.
See commit feed8e4bd9dc ("soc/intel/adl/acpi: add FSPI to DSDT") for
the corresponding ADL CL.
TEST=Built and tested on brya by verifying the error is gone.
