soc/intel/{adl, cmn/pcie}: Fix ASPM configuration enum definitions
As per PCI Express Base Specification 5.0 section 5.4.1.3 ASPM
Configuration
+-----------------------+-------------------------------+
| Field Description | ASPM Support |
+-----------------------+-------------------------------+
| 00b | No ASPM support |
+-----------------------+-------------------------------+
| 01b | L0s Supported |
+-----------------------+-------------------------------+
| 10b | L1 Supported |
+-----------------------+-------------------------------+
| 11b | L0s and L1 Supported |
+-----------------------+-------------------------------+
100b aka 0x4 is added by FSP to allow auto configuration (to avoid
conflicting with the PCI specification defined values).
Additionally, changed enum definition which is now meeting the FSP expectations better.
