[PATCH v3 3/6] arm: snapdragon: Add CONFIG_QCOM_SNAGBOOT_SUPPORT option

[Balaji Selvanathan]

Add CONFIG_QCOM_SNAGBOOT_SUPPORT to the boot0.h workaround choice
block to enable snagboot mode support on Qualcomm platforms.

This config option automatically selects the
required dependencies: QCOM_COMMAND_DB_OPTIONAL,
ENABLE_ARM_SOC_BOOT0_HOOK to enable early boot hooks, and SKIP_RELOCATE.
