[AArch64] Fix printf format warning in aarch64_print_operand


Hello,

This patch fixes the following warning in config/aarch64/aarch64.c:

.../gcc/config/aarch64/aarch64.c: In function âvoid aarch64_print_operand(FILE*, rtx, char)â:
.../gcc/config/aarch64/aarch64.c:3376:42: warning: format â%xâ expects argument of type âunsigned intâ, but argument 3 has type âlong unsigned intâ [-Wformat]

By adding the missing w to %wx.

Regression tested on aarch64-none-elf:aarch64.exp with no issues and
checked to ensure the warning clears.

Thanks,
James Greenhalgh
