There is some macro to identify the cross-compile-toolchain is hisi

[deepindeed2022]

I write some code, but the hisiv500 or himix200 don't support some macro code
/tmp/ccjlEhY5.s:145: Error: selected processor does not support pld [r3,#0x100]' in ARM mode`

So, I want ignore the code where use hisi cross compile toolchain, there are some macro could use?
