nios2: Fix unused variable warning
Fix the following compiler splat by adding __maybe_unused annotation to
the variable. Using this particular annotation has the least ugly impact
on the code compared to using ifdeffery.
arch/nios2/kernel/setup.c: In function 'nios2_boot_init':
arch/nios2/kernel/setup.c:107:7: warning: unused variable 'cmdline_passed' [-Wunused-variable]
char cmdline_passed[COMMAND_LINE_SIZE] = { 0, };
