arch: arm64: Remove unnecessary code in arm64_cpu_idle.S

Browse Source 
Summary:
- I noticed that irq is enabled explicitly in arm64_cpu_idle.S
- The code is unnecessary since tasks, including the idle task,
  are created with irq enabled in up_initial_state()

Impact:
- Should be none

Testing:
- qemu-armv8a:netnsh_smp_hv with qemu-7.2.4
