ASPM_OPT_COMPLIANCE: ASPM Optionality Compliance. This bit should be set to
1b in all Functions. Components implemented against certain earlier versions of this
specification will have this bit set to 0b. Software is permitted to use the value of this
bit to help determine whether to enable ASPM or whether to run ASPM compliance
tests.

RW_O
L1SELAT: L1 Exit Latency: Indicates the length of time this Port requires to complete
the transition from L1 to L0. The value 010b indicates the range of 2 us to less than 4
us.
000: Less than 1 us
001: 1 us to less than 2 us
010: 2 us to less than 4 us
011: 4 us to less than 8 us
100: 8 us to less than 16 us
101: 16 us to less than 32 us
110: 32 us-64 us
111: More than 64 us
Both bytes of this register that contain a portion of this field should be written
simultaneously in order to prevent an intermediate (and undesired) value from ever
existing.

L0SELAT: L0s Exit Latency: Indicates the length of time this Port requires to complete
the transition from L0s to L0.
000: Less than 64 ns
001: 64 ns to less than 128 ns
010: 128 ns to less than 256 ns
011: 256 ns to less than 512 ns
100: 512 ns to less than 1 us

MLS: This default value reflects gen1. Later the field may be changed by BIOS to allow
gen2 subject to Fuse enabled.
Defined encodings are:
0001b: 2.5 GT/s Link speed supported
0010b: 5.0 GT/s and 2.5 GT/s Link speeds supported
0011b: 8.0 GT/s and 5.0 GT/s and 2.5 GT/s Link speeds supported
