dt-bindings: net: dsa: sja1105: convert to YAML schema

Since the sja1105 driver no longer has any custom device tree
properties, the conversion is trivial.

+description:
+  The SJA1105 SPI interface requires a CS-to-CLK time (t2 in UM10944.pdf) of at
+  least one half of t_CLK. At an SPI frequency of 1MHz, this means a minimum
+  cs_sck_delay of 500ns. Ensuring that this SPI timing requirement is observed
+  depends on the SPI bus master driver.

-NXP SJA1105 switch driver
-=========================
-
-Required properties:
-
-- compatible:
-	Must be one of:
-	- "nxp,sja1105e"
-	- "nxp,sja1105t"
-	- "nxp,sja1105p"
-	- "nxp,sja1105q"
-	- "nxp,sja1105r"
-	- "nxp,sja1105s"
-
-	Although the device ID could be detected at runtime, explicit bindings
-	are required in order to be able to statically check their validity.
-	For example, SGMII can only be specified on port 4 of R and S devices,
-	and the non-SGMII devices, while pin-compatible, are not equal in terms
-	of support for RGMII internal delays (supported on P/Q/R/S, but not on
-	E/T).
-
-See Documentation/devicetree/bindings/net/dsa/dsa.txt for the list of standard
-DSA required and optional properties.
-
-Other observations
-------------------
-
-The SJA1105 SPI interface requires a CS-to-CLK time (t2 in UM10944) of at least
-one half of t_CLK. At an SPI frequency of 1MHz, this means a minimum
-cs_sck_delay of 500ns. Ensuring that this SPI timing requirement is observed
-depends on the SPI bus master driver.
