spi: dt-bindings: snps,dw-apb-ssi: Document Axiado AX3005

Browse Source 
The Axiado AX3005 SPI controller is software-compatible with the
Synopsys DesignWare APB SSI 1.01a programming interface.

Document the "axiado,ax3005-spi" SoC-specific compatible with
"snps,dwc-ssi-1.01a" as its fallback. This preserves identification of
the AX3005 integration while allowing the controller to use the
existing DesignWare APB SSI support.
