Subject: [PATCH] arch/x86/smbios: Add support for large memory capacity in
 type 16

Avoid SMBIOS type 16 Maximum Capacity showing incorrect
information when value of maximum capacity exceeds 32 bits by
extending the type.

Handle 0x0009, DMI type 16, 23 bytes
Physical Memory Array
	Location: System Board Or Motherboard
	Use: System Memory
	Error Correction Type: Single-bit ECC
	Maximum Capacity: 4 TB
	Error Information Handle: Not Provided
	Number Of Devices: 6

Tested=On OCP Crater Lake, the SMBIOS type 16 shows expected
Maximum Capacity.
