[PATCH v2 2/5] powerpc/boot: Fix crt0.S syntax for clang

[Joel Stanley]

Clang's assembler does not like the syntax of the cmpdi:

 arch/powerpc/boot/crt0.S:168:22: error: unexpected modifier on variable reference
         cmpdi   12,RELACOUNT at l
                              ^
 arch/powerpc/boot/crt0.S:168:11: error: unknown operand
         cmpdi   12,RELACOUNT at l
                   ^
Enclosing RELACOUNT in () makes it is happy. Tested with GCC 8 and Clang
8 (trunk).

Reported to clang as https://bugs.llvm.org/show_bug.cgi?id=38945
