88b05f9391 esp_adc_cal: Added ADC calibration component
Added component containg API that is able to correct raw ADC readings
into a voltage in mV. Also provided a helper function that combines
the process of getting the raw ADC1 reading then converting it to a
voltage in mV. In doing so, the adc1_get_voltage() function of the ADC
driver has been deprecated. Instead there is now adc1_get_raw to obtain
the raw ADC1 reading, and adc1_to_voltage() that gets the raw reading
and converts all in one function. Functions using the deprecated
adc1_get_voltage() have also been updated to use adc1_get_raw().

Conversion is based on ADC characteristics. The characteristics are based
on the ADC's v_ref, herefore the appropriate structure and functions have
been provided to obtain the ADC characteristics.

The existing ADC driver has also been modified by adding a function to
route the internal ADC reference voltage to a GPIO allowing users to measure
it manually.

Relevant documentation has also been updated

194d4e9ffd fix(touch_pad): modify touch pad read function and touch_pad_deinit
The touch pad read function taks too much time within spin lock waiting for the "done bit". (about 7.6ms as we tested)
So we try to use a mutex on the touch read function and any other functions might change the "done bit".

3b854fe46a deep sleep: implement wake up using ULP, EXT0, EXT1 sources
This adds the following APIs to enable various wakeup sources:
- esp_deep_sleep_enable_timer_wakeup
- esp_deep_sleep_enable_ulp_wakeup
- esp_deep_sleep_enable_ext0_wakeup
- esp_deep_sleep_enable_ext1_wakeup

And an API to start deep sleep:
- esp_deep_sleep_start

b1db2721dc driver: add rtc module and bugfix gpio32 gpio33
feature(rtc_module):add rtc module

1. add rtc io control API (pull,output and input)
2. add touch pad API (touch pad read and interrupt)
3. add adc1 API (the max width is 12 Bits and support attenuation)
4. add hall sensor API (support hall sensor read )
5. add dac API (the width is 8 Bits)

bugfix(gpio):gpio32 and gpio33 can not output and input

the gpio32 and gpio33 is initialize by librtc.a,and gpio_config not initialize the gpio as
digital gpio.they can not output and input,when users use gpio32 or gpio33.And there are some problems
about others driver ,when they use gpio32 or gpio33 as  matrix.
