lib: logic_pio: Add logic_pio_unregister_range() commit b884e2de2afc68ce30f7093747378ef972dde253 upstream. Add a function to unregister a logical PIO range. Logical PIO space can still be leaked when unregistering certain LOGIC_PIO_CPU_MMIO regions, but this acceptable for now since there are no callers to unregister LOGIC_PIO_CPU_MMIO regions, and the logical PIO region allocation scheme would need significant work to improve this.
