[ALSA] CS5535: shorter delays when accessing AC'97 codec registers

Modules: CS5535 driver

The 10 ms sleeps while waiting for AC'97 codec register reads/writes to
complete are excessive given the maxmium time is one AC'97 frame (~21 us).

With AC'97 codecs with integrated touchscreens (like the UCB1400) this
improves the interactive performance of the touchscreen.
