Fix a few issues found while running WHQL tests:

 - Assertion 1F27399E-30B9-44BC-8908-D6E6F3836212: FAILED. Enhanced Capability 
Header register
   of the PCI Express Enhanced Capabilities Absent Indicator table must be 
read-only .

   Solved in patch 1/4

Error Reporting Enable)
   in the Device Control register (offset 8h) in the PCI Express Capability 
table must be read-writable .
 - Assertion 5CBA2A63-A48E-4443-85FA-A7DCD8EA47BC: FAILED. Bit 1 (Non-Fatal 
Error Reporting Enable)
   in the Device Control register (offset 8h) in the PCI Express Capability 
table must be read-writable .
 - Assertion 0AB06F7C-59CB-4F9A-8363-B51B1ACAB54F: FAILED. Bit 2 (Fatal Error 
Reporting Enable)
   in the Device Control register (offset 8h) in the PCI Express Capability 
table must be read-writable .
 - Assertion E3834E4A-A7BD-410C-9A61-FA91770D2A71: FAILED. Bit 3 (Unsupported 
Request Reporting Enable)
   in the Device Control register (offset 8h) in the PCI Express Capability 
table must be read-writable 

   Solved in patch 2/4

 - Assertion 1587DC0B-FE59-494E-85B5-C2A59D0CC098: FAILED. Bit 6 (Common Clock 
Configuration)
