drivers/timer/xtensa_sys_timer: Add init/update hooks for asm2
The earlier xtensa layer put the timer initialization and update
directly into the interrupt handler, which is... weird. Under asm2,
it's just a regular ISR and needs to do the work in the driver.
Really, this driver needs a bunch of cleanup. The xtensa CPU timer is
two registers and one ISR: a global cycle count register, and a
compare register that will fire the IRQ when they match. There is
*way* too much code here.
