Implement task_poke_watchdogs

task_poke_watchdogs() should be called every 2ms (ticks 1 and 9) on both
master and slaves while in observation and active state and do the following:
1.  Every time called:  Enable/Reset the OCC heartbeat:  done by a write to
    OCB OCC Heartbeat Register (set count to 8ms)
2.  Every time called:  Reset memory deadman timer for 1 MCA (skip if not
    present and just wait until next call to check next MCA to keep same
    timing of reset per MCA regardless of # present)  Resetting the deadman
    is done by reading one of the memory performance counters, use one at
    SCOM offset 0x13C.  NOTE:  Will take 16ms (8 MCAs x 2ms) to reset all
    memory timers, this is fine since the shortest time the deadman timeout
    can be configured to is 28ms
3.  Every 4ms (on tick 1 only) :  Verify PGPE is still functional by reading
    PGPE Beacon from SRAM if after 8ms (2 consecutive checks) there is no
    change to the PGPE Beacon count then log an error and request reset.

In addition, this commit adds entries for the PGPE image header and shared
SRAM in the TLB, and partially reads PGPE image header parameters.
