[v4,0/5] Add PCIe support for SM8250 SoC

Hello,

This series adds PCIe support for Qualcomm SM8250 SoC with relevant PHYs.
There are 3 PCIe instances on this SoC each with different PHYs. The PCIe
controller and PHYs are mostly comaptible with the ones found on SDM845
SoC, hence the old drivers are modified to add the support.

This series has been tested on RB5 board with QCA6390 chipset connected
onboard.

NOTE: This series functionally depends on the following patch:
https://lore.kernel.org/linux-arm-kernel/[e-mail]/

I've dropped a similar patch in v2.

Thanks,
Mani

Changes in v4:

* Fixed an issue with tx_tbl_sec in PHY driver

Changes in v3:

* Rebased on top of phy/next
* Renamed ops_sm8250 to ops_1_9_0 to maintain uniformity

Changes in v2:

* Fixed the PHY and PCIe bindings
* Introduced secondary table in PHY driver to abstract out the common configs.
* Used a more generic way of configuring BDF to SID mapping
* Dropped ATU change in favor of a patch spotted by Rob
