ALSA: hda - Change the AZX_MAX_PCMS to 10

In hda_codec.c, it has define
"[HDA_PCM_TYPE_HDMI]  = { 3, 7, 8, 9, -1 },",
it support up to device 9 for HDMI.
But in hda_intel.c, it only define AZX_MAX_PCMS as 8.
So if it have 4 hdmi codecs, when run azx_attach_pcm_stream(),
it will show error "Invalid PCM device number 8", and "... number 9",
and return "-EINVAL".
We should change the AZX_MAX_PCMS to 10.
