Platform/RISC-V: Add PCD variables related to PCI

[wangy566]

Pcihostbridgelib uses the general PCD variable.
Like PcdPciBusMin PcdPciBusMax ...

These PCDs made part of generic RISC-V package itself , so that they don't need to be added for every platform in the future.

#211

@wangy566 : This is not correct. Both #211 and #212 have same commit to add the bit operation macro which is the reason for @hrw to ask that question. Actually please update the #200 itself with more commits to address comments instead of raising new PRs. You can force push latest changes to same branch which will reflect in the PR.

Also, I have not yet reviewed the changes. So, please don't add Reviewed-by tag. These tags are not necessary with github PR based review process. Only Signed-off tag is mandatory.
