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.

Currently, is_sys_clk_from_pll check sysclk source by reading codec
register value. And it will be invoked before updating dapm widget
power. In some machine driver, snd_soc_dai_set_sysclk is called in
dapm event to switch codec sysclk to RC clock in idle mode. And in
some use cases (such as syspend/resume) hw_params will not be called
when the dapm widget is powered up. As a result, is_sys_clk_from_pll
will return 0 although it is supposed to be 1.
To solve this, we let is_sys_clk_from_pll check sysclk sysclk_src
which is stored in private data and don't change the value of sysclk_src
when codec sysclk is switched to internal clock. The internal clock
can only be used in idle mode, so it sould be fine if we don't set
sysclk_src to internal clock.

System clock is necessary for rt5670 JD function. We assume system
clock source will be set in machine driver. So there are two things
left we should do in codec driver.
1. Set sysclk to codec internal clock in probe since machine driver
   may not do that before JD function is registered.
2. Power up PLL once sysclk source is switched to PLL.
