soc/intel/jsk: Move ME FSR structures to pertinent header
This patch moves ME host firmware status register structures to ME
header file. It also marks unused structure fields to reserved.
The idea here is to decouple ME specification defined structures from
the source file `.c` and keep those into header files so that in future
those spec defined header can move into common code.
The current and future SoC platform will be able to select the correct
ME spec header based on the applicable config. It might be also
beneficial if two different SoC platforms would like to use the same
ME specification and not necessarily share the same SoC directory.
