boot/arm-trusted-firmware: add optional host-dtc dependency

Browse Source 
Some ATF configurations, such as the ones for the STM32MP1 processor
family, require DTC during the build as Device Tree files are
used. Without dtc, the build fails:

/bin/sh: 1: dtc: not found
dtc version too old (), you need at least version 1.4.4
plat/st/stm32mp1/platform.mk:239: recipe for target 'check_dtc_version' failed
make[1]: *** [check_dtc_version] Error 1

To solve this, this commit implements a
BR2_TARGET_ARM_TRUSTED_FIRMWARE_NEEDS_DTC option, in a way that mimics
the BR2_TARGET_UBOOT_NEEDS_DTC option we already have for the U-Boot
package.
