[PATCH v3 0/3] arm64: dts: qcom: hamoa-iot-evk: Enable M.2 Key E connector

[Wei Deng]

Describe the PCIe M.2 Key E connector on the Hamoa IoT EVK. This is
the DTS half of [1]. The pcie-m2 sub-ID patch is sent independently
as [PATCH v2]; the W_DISABLE2# else-branch patch is dropped in favor
of Chen-Yu Tsai's series [2].

Depends on: [2]

Changes in v3:
- patch 1/3: add uart14_ep, usb_2_m2_ep and pcie4_port0_ep stub endpoints
  in hamoa.dtsi, so board DTS can reference them by label directly; remove
  superfluous comment (Konrad).
- patch 3/3: use &uart14_ep, &usb_2_m2_ep and &pcie4_port0_ep label
  references instead of re-defining port hierarchy in board DTS (Konrad).
- Link to v2: https://lore.kernel.org/r/20260723-hamoa-m2-dts-v2-v2-0-82254ac101fb@xxxxxxxxxxxxxxxx

Changes in v2:
- Split PATCH 1/3 of [1] into two commits (Dmitry).
- Add usb_2 HS port@0 (new patch 1/3) to pair with M.2 USB port@1.
- In patch 3/3: rename pcie4port0_ep -> pcie4_port0_ep (Konrad); add
  port@2 for the USB BT variant; remove unused vreg_wcn_0p95 /
  vreg_wcn_1p9 (sashiko). Konrad's v1 Reviewed-by is not carried:
  the new port@2 endpoint and vreg cleanup were not part of the v1
  review scope.
- Drop PATCH 3/3 of [1]; use [2] instead (Mani).
