AMD/Bettong: DSDT table: Reserved MMIO space for FCH
In current code, \_SB.PCI0 declare MMIO between TOM1 and 4GB.
This is not correct because higher MMIO space is reserved by \_SB rather than
\_SB.PCI0. For example:
[0xFEDC2000 - 0xFEDC5FFF] reserved for FCH I2C
[0xFEDC6000 - 0xFEDC8FFF] reserved for FCH UART
