Alexander Stein 91d1ff322c arm64: dt: imx95: Add TQMa95xxSA 
Add initial support for TQMa95xxSA module compatible to SMARC-2.
There is a common device tree for all variants with e.g. reduced CPU count.
It supports LPUART7 for console, CAN, PCIe I2C, SPI, USB3.0, USB2.0, Audio,
SDHC1/2 and QSPI as storage.
