This commit adds a new API ulp_reisv_reset() to enable reseting of the
ULP core from the main core. This is particularly necessary in case the
ULP crashes due to any reason. Earlier the only way to recover the ULP
was to do a power reset. This commit also adds new test cases which
exercise this scenario.
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.
