Fix memory leak in mixer_wait_event(). Also, poll should be
unblocked after increasing event_cnt in mixer_plugin, otherwise
event_cnt can become negative during read_event. Fix the same.

There does not really seem to be an usage for these dummy string,
so let's remove them.

memcpy() is arguably wrong when copying these string constants.
The string constants will usually just be as long as necessary,
so we might copy some random memory behind it and eventually crash.
Use strncpy() instead to avoid copying characters after the null
terminator. For some reason the strings in snd_ctl_card_info use
unsigned chars, so we need a cast to char* to make it compile
unfortunately...
This fixes the following compile error on ppc64le:
In function 'mixer_plug_get_card_info',
inlined from 'mixer_plug_ioctl' at mixer_plugin.c:371:15:
mixer_plugin.c:333:5: error: 'memcpy' forming offset [9, 16] is out of the bounds [0, 8] [-Werror=array-bounds]
333 | memcpy(card_info->id, "card_id", sizeof(card_info->id));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Not sure why that warning does not exist on other architectures.

Update the mixer framework to support plugins. Add ability for physical
card to have either kernel registered mixer controls or plugin
registered mixer control or both. Split mixer controls into two groups,
one for kernel registered (hw_grp) and the other for plugin registered
(virtual_grp).
