ALSA: emu10k1: stop doing weird things with HCFG in snd_emu10k1_emu1010_init()
This doesn't do anything snd_emu10k1_init() wouldn't do later, and none
of the things it does seem relevant for the function itself (which is
pretty much about setting up the FPGA). It was probably a Windows
driver behavior cargo-culting artifact.
