hw/openrisc: Initialize timer time at startup
The last_clk time was initialized at zero, this means when we calculate
the first delta we will calculate 0 vs current time which could cause
unnecessary hops.
This patch moves timer initialization to the cpu reset. There are two
resets registered here:
1. Per cpu timer mask (ttmr) reset.
2. Global cpu timer (last_clk and ttcr) reset, attached to the first
cpu only.
