{drivers,soc/intel/braswell}: Implement C_ENVIRONMENT_BOOTBLOCK support

No C_ENVIRONMENT_BOOTBLOCK support for Braswell is available.
Enable support and add required files for the Braswell Bootblock in C.

The next changes are made support C_ENVIRONMENT_BOOTBLOCK:
- Add car_stage_entry() function bootblock-c_entry() functions.
- Specify config DCACHE_BSP_STACK_SIZE and C_ENV_BOOTBLOCK_SIZE.
- Add bootblock_c_entry().
- Move init from car_soc_XXX_console_init() to bootblock_soc_XXX_Init()

Removed the unused cache_as_ram_main() and weak car_XXX_XXX_console_init()
