The ADC driver of IT81302 chip can support channels 0-7 & 13-16.
This PR adds to implement ADC channels 13-16.

The ADC sampling of it8xxx2 needs to read each channel in sequence,
so it needs to wait for an interrupt to read data in the loop
through k_sem_take().
In test_adc.c, k_timer_start() is used in the interval test, so we
need to use polling wait instead of k_sem_take() to wait, otherwise
it will cause kernel panic.
k_is_in_isr() can determine whether to use polling or k_sem_take()
at present.

Stop using redundant DEV_DATA/DEV_CFG macros and use dev->data
and dev->config instead.

Refactors all of the ADC drivers to use a shared driver class
initialization priority configuration, CONFIG_ADC_INIT_PRIORITY, to
allow configuring ADC drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are lmp90xxx, mcp320x, and mcux_adc16 drivers which have
dependencies on GPIO, SPI, and/or DMA drivers and must therefore
initialize later than the default device priority.

Create the pinmux phandle to the ADC driver node in the
devicetree. When the pinmux_pin_set function in
adc_it8xxx2_channel_setup can refer to the setting of
this phandle. It is more flexible to use.

This commit fixes the ADC driver flow. And add internal
reference voltage to ADC driver API. And correct the
data buffer that only need to store raw data.
