amdgpu/dc/dml: Support clang option for stack alignment
DML uses the compiler option -mpreferred-stack-boundary=4 to configure
a stack alignment of 16 bytes. Clang uses the option -mstack-alignment
instead, which expects as parameter the alignment in bytes, and not a
power of two like -mpreferred-stack-boundary.
Probe for both compiler options and use the correct one, similar to
what is done in arch/x86/Makefile.
