product/rddanielxlr: migrate to isys_romRD-INFRA-2020.11.09

Migrate from using mscp_rom module to isys_rom module as the boot ROM
for both SCP and MCP controllers. As there is no support yet for MCP
RAM firmware, the config data for the bootloader module is set to NULL.
The isys_rom module ensures that the MCP processor is held in a idle
state.
