soc/intel/pantherlake: Fix UFS ACPI _ADR calculation

This patch corrects the calculation of the _ADR value for the Intel UFS
controller in the `soc/ufs.h` header file.

The previous calculation incorrectly included a hardcoded value (0x0007)
in the lower bits of the _ADR. This is not in line with the Panther Lake
EDS specification (doc: 815002)

BUG=b:382243957
TEST=Able to build and boot google/fatcat.
> iasl -d /sys/firmware/acpi/tables/DSDT

Device (UFS)
    {
        Name (_ADR, 0x00170000)  // _ADR: Address
        Name (_DDN, "UFS Controller")  // _DDN: DOS Device Name
        Name (_DSD, Package (0x02)  // _DSD: Device-Specific Data
