arch/x86/smbios: Modify smbios type 9 data bus width

According to smbios spec DSP0134_3.6.0, data bus width indicates
eletrical bus width. But now every data bus width of slot
information shows 1 that represents "SlotDataBusWidthOther".

Tested=On OCP CraterLake, dmidecode -t 9 shows the expected results.
For example, before this patch result:
Handle 0x001E, DMI type 9, 19 bytes
System Slot Information
    Designation: SSD0_M2_Boot_Drive
    Type: x4 M.2 Socket 3
    Current Usage: In Use
    Length: Short
    Characteristics:
    	3.3 V is provided
    	PME signal is supported
    Bus Address: 0000:bc:00.0
    Data Bus Width: 1
    Peer Devices: 0

After this patch result:
Handle 0x001E, DMI type 9, 19 bytes
System Slot Information
    Designation: SSD0_M2_Boot_Drive
    Type: x4 M.2 Socket 3
    Current Usage: In Use
    Length: Short
    Characteristics:
    	3.3 V is provided
    	PME signal is supported
    Bus Address: 0000:bc:00.0
    Data Bus Width: 10
    Peer Devices: 0
