i2c: designware: Add ACPI HID for DWAPB I2C controller on FUJITSU-MONAKA

Enable DWAPB I2C controller support on FUJITSU-MONAKA.
This will be used in the FUJITSU-MONAKA server scheduled
for shipment in 2027.

The DSDT information obtained when verified using an
in-house simulator is presented below.

     Device (SMB0)
     {
         Name (_HID, "FUJI200B")  // _HID: Hardware ID
         Name (_UID, Zero)  // _UID: Unique ID
         ...
         Name (_CRS, ResourceTemplate ()
         {
             Memory32Fixed (ReadWrite,
                 0x2A4B0000,         // Address Base
                 0x00010000,         // Address Length
                 )
             Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, )
             {
                 0x00000159,
             }
         })
         ...
     }

The expression SMB0 is used to indicate SMBus HC#0,
a string of up to four characters.

Created the SMB0 object according to the following
specifications:
