  hw/xtensa: xtfpga: raise CPU number limit (2019-01-28 11:55:20 -0800)

----------------------------------------------------------------
target/xtensa: SMP updates and various fixes

- fix CPU wakeup on runstall changes; expose runstall as an IRQ line;
- place mini-bootloader at the BSP reset vector;
- expose CPU core frequency in XTFPGA board FPGA register;
- rearrange access to external interrupts of xtensa cores;
- add MX interrupt distributor and use it on SMP XTFPGA boards;
- add test_mmuhifi_c3 xtensa core variant;
- raise number of CPUs that can be instantiated on XTFPGA boards.
