powerpc/powermac: Mark variable x as unused
[ Upstream commit 5a4b475cf8511da721f20ba432c244061db7139f ]
Since the value of x is never intended to be read, declare it with gcc
attribute as unused. Fix warning treated as error with W=1:
arch/powerpc/platforms/powermac/bootx_init.c:471:21: error: variable ‘x’ set but not used [-Werror=unused-but-set-variable]
