[PATCH V3 5/8] arm64: dts: imx95-19x19-evk: Describe the PCIe M.2 Key E connector

[Sherry Sun (OSS)]

From: Sherry Sun <sherry.sun@xxxxxxx>

The i.MX95-19x19-EVK has the PCIe M.2 Mechanical Key E connector to
connect wireless connectivity cards over PCIe and UART interfaces. Hence,
describe the connector node and link it with the PCIe 0 Root Port and
LPUART5 nodes through graph port/endpoint.
