H A Dsetup.cdiff 59dc2d94bc12dac53a5d2368ad97ca24e7cc5682 Thu Nov 03 02:01:22 CDT 2022 Chen Lifu <chenlifu@huawei.com> powerpc/powermac: Fix symbol not declared warnings

1. ppc_override_l2cr and ppc_override_l2cr_value are only used in
l2cr_init() function, remove them and used *l2cr directly.
2. has_l2cache is not used outside of the file, so mark it static and
do not initialise statics to 0.

Fixes the following warnings:

arch/powerpc/platforms/powermac/setup.c:73:5: warning: symbol
'ppc_override_l2cr' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:74:5: warning: symbol
'ppc_override_l2cr_value' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:75:5: warning: symbol
'has_l2cache' was not declared. Should it be static?
