audiocore: Fix small race window in get_fifo_read_value_blocking 6f155ebb55 
In theory, the FIFO interrupt could occur after getting the
fifo_read_value and reenabling interrupts, but before __wfi is called,
causing a deadlock. Fix this by calling __wfi with interrupts still
disabled. It will return immediately if an interrupt is pending.

Add two __nop to ensure that the CPU has enough instructions between
enabling interrupts and disabling them again at the top of the loop.

board: Increase C heap to 12k e72cfa8d3b 
Loading a btree database with actual data in it needs more than 8k. 12k
seems to work for now.
