ALSA: emu10k1: make E-MU FPGA writes potentially more reliable

We did not delay after the second strobe signal, so another immediately
following access could potentially corrupt the written value.

This is a purely speculative fix with no supporting evidence, but after
taking out the spinlocks around the writes, it seems plausible that a
modern processor could be actually too fast. Also, it's just cleaner to
be consistent.
