ALSA: hda: Reset all SIE bits in INTCTL

Old code resets SIE for up to 8 streams using byte accessor, but
register is laid out in following way:

31 GIE
30 CIE
29:x Reserved
x-1:0 SIE

If there is more than 8 streams, some of them may and up with enabled
interrupts. To fix this just clear whole INTCTL register when disabling
interrupts.
