Darian Leung 0c9e2c0fba esp_adc_cal/Remove lookup table 
This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.

Example: ADC1

This test code shows how to configure ADC1 and read the voltage connected to GPIO pin.

ADC1 functions:

ADC1_CHANNEL_6: GPIO34, voltage range [0V..1.1V], the data range [0..4095]

Test:

Please connect the test voltage to GPIO34
