Make the microblaze arch's clockevent driver initialize these fields properly. This patch alone doesn't introduce any change in functionality as the clockevents core still looks exclusively at the (untouched) ->min_delta_ns and ->max_delta_ns. As soon as this has changed, a followup patch will purge the initialization of ->min_delta_ns and ->max_delta_ns from this driver.

Thus, the arch specific headers can be removed and the asm-generic header can be used directly via generic-y. The headers removed from uapi don't need to be added to generic-y in the uapi Kbuild in order to get exported, as they are already listed in mandatory-y. Also order the generic-y list alphabetically.
