acpi/acpi: update ACPI_DBG2_PORT_SERIAL_16550 subtype
The Microsoft Debug Port Table 2 (DBG2) specification says that the serial port subtype 0x00 should only be used for I/O-mapped 16550 compatible UARTs. The subtype 0x12 is a superset of that, and supports specifying MMIO vs IO and the register access size via the generic address structure. Rename the subtype 0x00 definition to ACPI_DBG2_PORT_SERIAL_16550_IO_ONLY and add the subtype 0x12 definition as new ACPI_DBG2_PORT_SERIAL_16550, so that the acpi_write_dbg2_uart function will write the correct subtype for the generic 16550 UART.
