We have been using rt5640.c codec driver with RT5642 codec chip before commit
022d21f0 ("ASoC: rt5640: add rt5639 support"). That commits starts using
device ID reading in reset register for adding device specific controls and
routes runtime.

Now since device ID appears to be different between RT5640 and RT5642 the
driver doesn't add those controls and routes that are valid also on RT5642.

Fix this by adding a device ID found by debugging and minimal code for
supporting RT5642.

Add a device tree match table. This serves to make the driver's support
of device tree more explicit. Perhaps the fallback for DT matching to
using the i2c_device_id table will go away one day, since it fails in
face of devices from different vendors with the same name.

There is no need for the CODEC to go to standby on resume since the core will
power it up as needed and in any case it is an idle_bias_off CODEC so would
normally sit with bias off while idle.

The ACPI_PTR() macro evaluates to NULL if ACPI is disabled and hence the
ACPI match table won't be used, causing the compiler to complain. Avoid
this by protecting the table using an #ifdef CONFIG_ACPI.

Modify the RT5640 driver to parse platform data from device tree. Write
a DT binding document to describe those properties.

Slight re-ordering of rt5640_i2c_probe() to better fit the DT parsing.

Since ldo1_en is optional, guard usage of it with gpio_is_valid(), rather
than open-coding an if (gpio) check.
