Jinyang He c0aac3a51c MIPS: KASLR: Avoid endless loop in sync_icache if synci_step is zero 
Most platforms do not need to do synci instruction operations when
synci_step is 0. But for example, the synci implementation on Loongson64
platform has some changes. On the one hand, it ensures that the memory
access instructions have been completed. On the other hand, it guarantees
that all prefetch instructions need to be fetched again. And its address
information is useless. Thus, only one synci operation is required when
synci_step is 0 on Loongson64 platform. I guess that some other platforms
have similar implementations on synci, so add judgment conditions in
`while` to ensure that at least all platforms perform synci operations
once. For those platforms that do not need synci, they just do one more
operation similar to nop.
