Subject: [PATCH 7/9] media/radio: fix trust CONFIG IO PORT

From: Randy Dunlap <rdunlap@...otime.net>

Modify radio-trust to use HEX_STRING(CONFIG_RADIO_TRUST_PORT)
so that the correct IO port value is used.

Fixes the IO port value that is used since this is hex:
CONFIG_RADIO_TRUST_PORT=350
but it was being interpreted as decimal instead of hex.
