xpp: Add info to astribank_tool -Q

* In MPP serial protocol add support for SER_STAT_GET command
* Use it to query firmware for:
  - FPGA build configuration number (1 - old main, 2 - new main)
  - Watchdog timer state bit (ready/expired)
  - XPD Alive timer state bit (yes/no)
* Also cleanup the code in mpps_card_info():
  - In all MPP serial commands the send/recive buffers must
    have identical size
  - No need to alias struct pointers to byte-buffers, just use
    the structs themselves as buffers.
