ALSA: emu10k1: apply channel delay hack to all E-MU cards

Evidently, the channel delay bug exists in all E-MU cards; it's in the
Hana FPGA program, and was never fixed.

Note that the implementation is somewhat lazy - to localize the code
paths, we actually waste a GPR and a DSP instruction by keeping two
delay registers for the same physical source.
