Fix array-bound compilation warnings
Resolves : the warray bounds warning during compilation
/build/libc/include/string.h:34:16: warning: '__builtin_memset' offset [0, 2097151] is out of the bounds [0, 0] [-Warray-bounds]
34 | #define memset __builtin_memset
hw/fsp/fsp.c:1855:9: note: in expansion of macro 'memset'
1855 | memset(fsp_tce_table, 0, PSI_TCE_TABLE_SIZE);
use volatile pointer to avoid optimization introduced with gcc-11 on constant
address assignment to pointer.
