Suzuki K Poulose ff11f5bc5a coresight tmc etr: Detect address width at runtime
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.
