trustfence: repurpose TRUSTFENCE_GPIO_ENABLE to contain the GPIO name 

Now all platforms support setting the GPIO name instead of an index
as the configuration for the GPIO-enabled secure console.

Repurpose the TRUSTFENCE_GPIO_ENABLE macro to directly set the GPIO
name.

Also take the opportunity to remove TRUSTFENCE_GPIO_ENABLE and
TRUSTFENCE_CONSOLE_PASSPHRASE_ENABLE commented definitions from bbclass
and conf files, and remove a duplicated TRUSTFENCE_CONSOLE_DISABLE
definition from ccmp1.inc.
