Handle race condition between PSU/FIFO interface.
It fixes these two problems
1. Protect global interrupt flags by putting them in critical section
2. Disable inteerupts before sending the ACK for timer chipop. Otherwise
other high priority thread can interrupt it if there is a interrupt on FIFO.
On slow soft-fsi based systems, taking initial data from FIFO may take time
in command receiver thread.
