Building xtensa kernel with gcc-10 produces the following warnings:
arch/xtensa/kernel/xtensa_ksyms.c:90:15: warning: conflicting types
for built-in function ‘__sync_fetch_and_and_4’;
expected ‘unsigned int(volatile void *, unsigned int)’
[-Wbuiltin-declaration-mismatch]
arch/xtensa/kernel/xtensa_ksyms.c:96:15: warning: conflicting types
for built-in function ‘__sync_fetch_and_or_4’;
expected ‘unsigned int(volatile void *, unsigned int)’
[-Wbuiltin-declaration-mismatch]
Fix declarations of these functions to avoid the warning.
