soc/intel/adl/acpi: add FSPI to DSDT

A previous CL ("Add missing ACPI device path names",
commit d22500f0c61f8c8e10d8f4a24e3e2bf031163c07) caused some errors
from the Kernel on Brya devices (see Tim's comment on patchset 8):
> ACPI Error: AE_NOT_FOUND, While resolving a named reference
> package element - _SB_.PCI0.FSPI

FSPI is defined in src/soc/intel/alderlake/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.

TEST=Built and tested on brya by verifying the error is gone.
BUG=b:231582182
