+ * Description:
+ *
+ *   Initialize and register Omnibus F4's MAX7456 OSD chip. The wiring
+ *   isn't configurable, but we use macros anyway because some of the
+ *   values are referred to in more than one place. And also, because
+ *   that's generally what NuttX does.
+ *
+ *   In particular, the slave-select pin is defined by us, but
+ *   controlled elsewhere as part of the SPI machinery. This is an odd
+ *   thing in our case because nothing else is using the SPI port, but
+ *   that's not the general presentation so I'm staying consistent
+ *   with the pattern.
