[PATCH v2 0/5] PCI: qcom: Add PCIe support for Shikra SoC

[Sushrut Shree Trivedi <sushrut.trivedi@oss.qualcomm.com>]

Add PCIe support for Shikra target, by adding dt-bindings for phy,
controller and corresponding phy & controller drivers/device-tree
changes.

Shikra RC is connected to TC9563 PCIe switch on all three
EVK variants: CQS, CQM and IQS. The individual downstream ports
of TC9563 connect like below:

DSP1: M.2 B-Key for 5G Modem
DSP2: M.2 M-Key for NVMe
DSP3: Embedded ethernet device

Power and reset to M.2 B and M.2 M slot are controlled via
TC9563 GPIO's. Since TC9563 GPIO driver from Alex is still
under active review, current series only contains basic PCIe
enablement for the controller / PHY. TC9563 enablement changes
would be posted as a separate series once the GPIO driver is
ready.
