Due to a hardware issue ULP support on S3 is temporarily disabled until a fixed is released.
Running ULP + sleep together can potentially cause permanent damage to the chip.
This commit refactors the ulp component.
Files are now divided based on type of ulp, viz., fsm or risc-v.
Files common to both are maintained in the ulp_common folder.
This commit also adds menuconfig options for ULP within the ulp
component instead of presenting target specific configuations for ulp.
