Add a couple of new debugfs entries "ipc_flood_count"
and "ipc_flood_duration_ms" that can be used to
execute the IPC flood test. "ipc_flood_count" floods the DSP
with the number of test IPCs specified and ipc_flood_duration_ms
floods the DSP with test IPC's for the duration(in ms) specified.
The test stats such as average, min and max IPC response times
are logged in the dmesg and saved in the debugfs entry cache buffer.

HDA_DEV_ASOC type codec device refcounts are managed differently
from HDA_DEV_LEGACY devices. The refcount is released explicitly
in snd_hdac_ext_bus_device_remove() for ASOC type devices.
So, remove the put_device() call in snd_hda_codec_dev_free()
for such devices to make the refcount balanced. This will prevent
the NULL pointer exception when the codec driver is released
after the card is freed.

This tablet has an incorrect acpi identifier just like
Thinkpad10 tablet, which is why it is trying to load the RT5640 driver
instead of the RT5762 driver. The RT5640 driver, on the other hand, checks
the hardware ID, so no driver are loaded during boot. This fix resolves to
load the RT5672 driver on this tablet during boot. It also provides the
correct IO configuration, like the jack detect mode 3, for 1.8V pullup. I
would like to thank Pierre-Louis Bossart for helping with this patch.
