ASoC: sh: fsi: Document SoC-specific bindings

The documentation only mentioned the generic fallback compatible
property.
Add the missing SoC-specific compatible properties, some of which are
already in use.

Also fix a small typo, while we're at it.

 Renesas FSI
 
 Required properties:
-- compatible                   : "renesas,sh_fsi2" or "renesas,sh_fsi"
+- compatible                   : "renesas,fsi2-<soctype>",
+                                 "renesas,sh_fsi2" or "renesas,sh_fsi" as
+                                 fallback.
+                                 Examples with soctypes are:
+                                   - "renesas,fsi2-r8a7740" (R-Mobile A1)
+                                   - "renesas,fsi2-sh73a0" (SH-Mobile AG5)
 - reg                          : Should contain the register physical address and length
 - interrupts                   : Should contain FSI interrupt
 
-- fsia,spdif-connection                : FSI is connected by S/PDFI
+- fsia,spdif-connection                : FSI is connected by S/PDIF
 - fsia,stream-mode-support     : FSI supports 16bit stream mode.
 - fsia,use-internal-clock      : FSI uses internal clock when master mode.
