Merge remote-tracking branch 'remotes/xtensa/tags/20180122-xtensa' into staging

target/xtensa updates:

- make mini-bootloader independent of the initial CPU state;
- add noMMU XTFPGA variants;
- add two noMMU cores: de212 and sample_controller;
- fix issues reported by coverity against xtensa translator and disassembler.
