ls-ecaps: Correct the link state reporting

ls-ecaps: Correct the link state reporting

PCIe r6.0, sec 7.9.26.4.2 "Link IDE Stream Status Register defines"
the link state as:

0000b Insecure
0010b Secure

The same definition applies to selective streams as well.
The existing code wrongly assumes "secure" is 0001b, fix that for both
link and selective streams.

While at this, add missing "Selective IDE for Configuration Requests Enable".
Also fix the base and limit parsing for the memory and RID ranges.

Fixes: 42fc4263ec0e ("ls-ecaps: Add decode support for IDE Extended Capability")
