arm64/common: Critical Section Optimization.

Browse Source 
Replace critical_section with spinlock.
The benefits of doing this are:

1. It makes the code logic clearer, with different resources protected by different locks.

2. It improves system responsiveness and avoids contention issues caused by acquiring the same large lock.
