Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

acpi_device_id are not supposed to change at runtime. All functions
working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.

Idealy PLL will be set in machine driver if MCLK doesn't meet the
requirement of codec. To let the codec driver be more general, we
can use a common PLL setting once sysclk/pll doesn't set properly
in machine driver.

We will set some volatile registers in jack detection function. But
those volatile registers will be clear in rt5665_calibrate function
because we set cache bypass and reset codec in rt5665_calibrate function.
This patch add a flag to make sure that rt5665_calibrate is done
before starting jack detection.

With gcc 4.1.2:
sound/soc/codecs/rt5665.c: In function ‘rt5665_i2s_pin_event’:
sound/soc/codecs/rt5665.c:2610: warning: ‘mask1’ may be used uninitialized in this function
sound/soc/codecs/rt5665.c:2610: warning: ‘val2’ may be used uninitialized in this function
sound/soc/codecs/rt5665.c:2610: warning: ‘val1’ may be used uninitialized in this function
The first one is currently a false positive, as rt5665_i2s_pin_event()
is never called with snd_soc_dapm_widget.shift set to a value not
handled by the switch() statement. But that may change, so
preinitialize mask1 to fix this, like is already done for mask2.
The last two are false-positives, the compiler is just not smart enough
to notice the mask and val variables are always used together.
