There is a power saving mechanism in rt5670. It will turn off some
unused power when MCLK is not present. We call that "MCLK detection"
and it should be enabled by default.

We force enable "Mic Det Power" when a jack is inserted. Also, we
set codec idle_bias_off = true. As a result, codec driver will not
suspend as we expect.
On Braswell, we don't need the jack detection when suspend but need
it after resume, so export the jack suspend/resume APIs which are
provided for machine driver to control during suspend/resume.

This patch adds the IRQ function support of rt5670. We use a flag
named dev_gpio in platform data to inform codec driver if the IRQ
function is used or not. Also, we export rt5670_set_jack_detect
for machine driver to pass the jack point.

When codec is in slave mode, ASRC can suppress noise for asynchronous
MCLK and LRCLK or special I2S format. This patch defines an API to select
the clock source for specified filters. And the codec driver will turn on ASRC
for these filters if ASRC is selected as their clock source.

The previous definition of registers 0x84 and 0x85 doesn't match the datasheet.
So this patch removes the wrong definition and writes a new one for the two
registers.

Currently, we will configure dmic related pin definition if pdata.dmic_en
is true. However, there is no disable option in the enum. So, any dmic is
used, all 3 dmic related pins will be configured. It may cause unexpected
pin definition. This patch adds a disable item for each dmic enum and
take it as default. So the driver will not set the pin configuration if
we don't set dmicx_data_pin in platform data.

rt5672 is very similar to rt5670. Therefore we use one codec driver
to support both codecs. The difference between rt5670 and rt5672 is
there is some difference in their dapm routing table.
