Currently Intel queensbay fsp initializes a CAR size with only 4KiB, which is not enough when dm pci is enabled before relocation. Change arch/x86/start.s to reserve a small size before fsp_init() is called and some bigger size after fsp_init() which can be configured via the exisiting CONFIG_MALLOC_F_LEN.
