Heiko Carstens 8218827b73 scripts/min-tool-version.sh: raise minimum clang version to 14.0.0 for s390
Before version 14.0.0 llvm's integrated assembler fails to handle some
displacement variants:

arch/s390/purgatory/head.S:108:10: error: invalid operand for instruction
 lg %r11,kernel_type-.base_crash(%r13)

Instead of working around this and given that this is already fixed
raise the minimum clang version from 13.0.0 to 14.0.0.
