soc/intel/pantherlake: Add option to enable UFS controller
This patch adds a Kconfig option to enable the UFS controller for
mainboards using the Intel Panther Lake-UH SoC.
By default, the UFS controller is disabled as it is not supported by
other SoC configurations. This prevents accidental enabling of the
UFS controller on unsupported platforms.
BUG=b:379828045
TEST=Built google/fatcat with and without UFS enabled.
