Pull bootconfig updates from Masami Hiramatsu:
- Fix ftrace2bconf.sh tool for checking event enable status correctly
- Add CONFIG_BOOT_CONFIG_FORCE to apply bootconfig without 'bootconfig'
boot parameter
- Enable CONFIG_BOOT_CONFIG_FORCE by default if a bootconfig is
embedded in the kernel
- Increase max number of nodes of bootconfig to 8192
