soc/intel/xeon_sp: Clear reserved field in SRAT
During the ACPI dump of the System Resource Affinity Table (SRAT), it
was noticed that the reserved field within the Memory Affinity structure
contained a non-zero value. This commit addresses the issue by
performing a memset to zero on the reserved field, ensuring the
avoidance of any potential problems arising from garbage values.
TEST= Build for ibm/sbp1 & make sure SRAT Memory Affinity entries
reserved fields read zeroes
