The spec says this:
P0 tracing support field. The permitted values are:
0b00 Tracing of load and store instructions as P0 elements is not
supported.
0b11 Tracing of load and store instructions as P0 elements is
supported, so TRCCONFIGR.INSTP0 is supported.
All other values are reserved.
The value we are looking for is 0b11 so simplify this. The double read
and && was a bit obfuscated.
