[ptxdist] [PATCH 1/2] tf-a: add new host-tf-a recipe

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

FIP is becoming the standard for firmware booted by ARM Trusted
Firmware. While TF-A provides a fip target to assemble such images,
building them outside the TF-A build by means of fiptool (e.g. via
genimage[0]) can provide more flexibility.
Add a host-tf-a rule to facilitate this.
