TMC in Coresight SoC-600 advertises the AXI address width
in the device configuration register.
Bit 16 - AXIAW_VALID
0 - AXI Address Width not valid
1 - Valid AXI Address width in Bits[23-17]
Bits [23-17] - AXIAW. If AXIAW_VALID = b01 then
0x20 - 32bit AXI address bus
0x28 - 40bit AXI address bus
0x2c - 44bit AXI address bus
0x30 - 48bit AXI address bus
0x34 - 52bit AXI address bus
Use the address bits from the device configuration register, if
available. Otherwise, default to 40bit.
