ulp: refactor ulp component

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.
