ok.

"PCI: qcom: Remove PCIE20_ prefix from register definitions"
Fixing it, by using the right macro PARF_SLV_ADDR_SPACE_SIZE
and removing the unused PARF_SLV_ADDR_SPACE_SIZE_2_3_3.


Commit message should be imperative.

ok, will send v3.


Without this pcie bring up on IPQ8074 is broken now.

This could be wrapped in the above line itself.
