ARC: opencode arc_request_percpu_irq
- The idea is to remove the API usage since it has a subltle
design flaw - relies on being called on cpu0 first. This is true for
some early per cpu irqs such as TIMER/IPI, but not for late probed
per cpu peripherals such a perf. And it's usage in perf has already
bitten us once: see c6317bc7c5ab
("ARCv2: perf: Ensure perf intr gets enabled on all cores") where we
ended up open coding it anyways
- The seeming duplication will go away once we start using cpu notifier
for timer setup
