chip/host: Add spi+trng support, and add gpio func

This adds fake SPI Master and TRNG support to the
host target.
This change also adds the missing emulated gpio
interface function.

Although general purpose, these changes are setup for
allowing fuzzing of the FPMCU specific host commands.
Thus, they do not impact any outstanding code.
