libplatsupport: hifive ltimer refactor - Introduce two new helper functions `helper_fdt_alloc_simple`, `create_ltimer_simple` These are only used when there's 1 reg and 1 irq to register. - Refactor hifive timers to use these helper functions. - Nit: init time_h explicitly instead of being calloc'd

libplatsupport: Refactor the internal handle_irq Now that the handle_irq functions are no longer externally visible, this commits refactors the handle_irq functions so that they can be accessed internally. Also add logic to invoke the user supplied callbacks after handling the timer IRQ.

libplatsupport: Remove handle_irq from ltimers The 'handle_irq' function is no longer necessary and shouldn't be called externally as the IRQs will be managed by the IRQ handling functions of the IRQ interface.

libplatsupport: Allow user callbacks for ltimer With the IRQ changes to the ltimer, IRQs are now managed internally. This poses a problem with the management of the time manager and other services which rely on having known that an interrupt arrived for the timers. This also isn't a good idea as it presents a leaky abstraction in that the services infers events based on interrupts received. This commit adds the ability to allow users to supply a callback that'll be called when certain events occur for the timer, e.g. timeouts and etc.

libplatsupport: Add IRQ register logic to ltimers This commit adds IRQ registration logic to the ltimer driver level. Instead of treating interrupt allocation being a OS/environment specific thing, this commit now uses the OS/environment agnostic IRQ interface to register these interrupts. Also fix bugs/clean-up the logic of the init and destroy functions.
