PATCH 1/1 arch: m32r: include: asm: add generic cmpxchg64() definition

Need define cmpxchg64(), so use generic one.

The related error (with allmodconfig):

drivers/block/blockconsole.c: In function ‘bcon_advance_console_bytes’:
drivers/block/blockconsole.c:164:2: error: implicit declaration of function ‘cmpxchg64’ [-Werror=implicit-function-declaration]
