xtensa: fix __sync_fetch_and_{and,or}_4 declarations
[ Upstream commit 73f9941306d5ce030f3ffc7db425c7b2a798cf8e ] 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.
