Message

This contains multiple fix for PCIe qcom driver.
Some optional reset and clocks were missing.
Fix a problem with no PARF programming that cause kernel lock on load.
Add support to force gen 1 speed if needed. (due to hardware limitation)
Add ipq8064 rev 2 support that use a different tx termination offset.

v5:
* Split PCI: qcom: Add ipq8064 rev2 variant and set tx term offset

v4:
* Fix grammar error across all patch subject
* Use bulk api for clks
* Program PARF only in ipq8064 SoC
* Program tx term only in ipq8064 SoC
* Drop configurable tx-dempth rx-eq
* Make added clk optional

v3:
* Fix check reported by checkpatch --strict
* Rename force_gen1 to gen

v2:
* Drop iATU programming (already done in pcie init)
* Use max-link-speed instead of force-gen1 custom definition
* Drop MRRS to 256B (Can't find a realy reason why this was suggested)
* Introduce a new variant for different revision of ipq8064
