arm: ls1021a: mask interrupts before entering deep sleep
Before entering deep sleep, interrupts should be masked. Or,
unexpected interrupts may block the process of deep sleep.
So, mask interrupts by the following steps:
1. Mask interrupts to RCPM
2. Disable the GIC
This will make deep sleep more stable.
