plat/sgm775: Add support for dynamic config using fconf
1. Necessary changes to platform makefile to include fw_config
device tree and package it in fip.bin
2. Removed hw_config node from fw_config dts as there is no
HW_CONFIG device tree source for sgm775
3. Added mbedtls_heap related properties for TBBR functionality
