riscv: Suppress invalid coverity errors
Coverity is detecting 'sp' as a variable which has not been initialized. This is obviously not correct, so this patch *TRIES* to mark it as false I'm not positive that this will work because the annotation needs to go on the line above the error, but this error is inside of a # define. Does the whole #define count as one line? Can it go on the line above the #define in the .h file? Does it have to precede every line where the #define is used? The documentation doesn't make this clear. Should suppress coverity issues: 1368525 & 1368527 uninit_use: Using uninitialized value sp.
