There are two different PCIe controllers and PHYs on SM8450, one having
one lane and another with two lanes. Add support for both PCIe
controllers

Changes since v5:
 - Rebase on 5.17-rc1
 - Drop external dependencies. The pipe_clk rework takes too much time
   to be reviewed. SM8450 works with the current pipe_clk multiplexing
   code. Fixing pipe_clk will be handled separately.
 - Drop interconnect support. It will be handled separately for all
   generations requiring interconnect usage.

Changes since v4:
 - Add PCIe1 support
 - Change binding accordingly, to use qcom,pcie-sm8450-pcie0 and
   qcom,pcie-sm8450-pcie1 compatibility strings
 - Rebase on top of (pending) pipe_clock cleanup/rework patchset

Changes since v3:
 - Fix pcie gpios to follow defined schema as noted by Rob
 - Fix commit message according to Bjorn's suggestions

Changes since v2:
 - Remove unnecessary comment in struct qcom_pcie_cfg

Changes since v1:
 - Fix capitalization/wording of PCI patch subjects
 - Add missing gen3x1 specification to PHY table names
