[PATCH v3 2/2] arm64: dts: ls1012a: add DTS for TQMLS1012al module with MBLS1012AL board

[Alexander Stein]

From: Matthias Schiffer <matthias.schiffer@tq-group.com>

Add initial support for TQMLS1012AL module mounted on MBLS1012AL.
It supports UART1 for console, PCIe, I2C, USB, µSD card (default), SATA
and QSPI.
There is an alternative ordering option which provides an eMMC instead of
an SD card. This uses a different DT instead.
Due missing Packet Forwarding Engine (PFE) driver support, there is no
support for Ethernet so far.

Changes in v3:
* Sorted i2c nodes according their address
* Delete SD card specific properties from eMMC configuration
* Remove duplicated properties
* Sorted alias entries alphabetically
* Add 1.8V vcc supply for SPINOR flash
* Implement PCIE and WLAN power supplies as regulator, both 1.8V and 3.3V
* Rename regulators accordingly to the power rail signal name
* Renamed GPIO expander node names (gpio@)

Changes in v2:
* Be a bit more specific with lm75 compatible
* Remove m25p,fast-read from spi-nor flash

Subject: It's dt-bindings. Also double bindings is redundant.
