[PATCH v2 0/3] arm64: dts: qcom: add the Xiaomi Mi Pad 5 Pro 5G

The Mi Pad 5 Pro 5G (enuma, 2021) is the modem-equipped variant of the
Mi Pad 5 Pro (elish). The two boards share a design, so this describes
enuma as sm8250-xiaomi-elish-common.dtsi plus the three things that
differ: the board ID the bootloader matches on, the panel compatible and
the WiFi board data variant.

Unlike elish, enuma shipped with a single display variant, so there is
one device tree rather than a per-panel pair. The vendor device trees key
the touch configuration to a display maker, and enuma declares a single
entry against elish's three:

  https://github.com/MiCode/kernel_devicetree/blob/elish-r-oss/qcom/enuma-sm8250.dtsi#L309
  https://github.com/MiCode/kernel_devicetree/blob/elish-r-oss/qcom/elish-sm8250.dtsi#L294

The panel itself is the same part elish uses: both trees pull in the
same dsi-panel-k81-42-02-0a-video.dtsi, so the new
xiaomi,enuma-csot-nt36523 compatible falls back to
xiaomi,elish-csot-nt36523, leaving room to handle any difference that
turns up later without requiring a device tree change.

The WiFi board data is already upstream in ath11k-firmware as
bus=pci,qmi-chip-id=0,qmi-board-id=255,variant=Xiaomi_Pad_5Pro_5G
(QCA6390 hw2.0 board-2.bin, commit 235d09a5e111).

Tested on the device: the panel and WiFi come up and perform as expected
under postmarketOS.

The fingerprint sensor, PCIe2/modem and touchscreen this board also
provides are left out here; they depend on bindings that are not upstream
yet and will follow separately.
