The migration tests spend a lot of time waiting for a sign of live of the guest on the serial console. The aarch64 migration code only outputs "B"s every couple of seconds (at least it takes more than 4 seconds between each characeter on my x86 laptop). There are a lot of migration tests, and if each test that checks for a successful migration waits for these characters before and after migration, the wait time sums up to multiple minutes! Let's use a shorter delay to speed things up. While we're at it, also remove a superfluous masking with 0xff - we're reading and storing bytes, so the upper bits of the register do not matter anyway. With these changes, the test runs twice as fast on my laptop, decreasing the total run time from approx. 8 minutes to only 4 minutes!
