Let's read #BL602's Internal Temperature Sensor with Apache #NuttX OS

https://github.com/lupyuen/bl602_adc

#BL602's Internal Temperature Sensor is connected to the Analog-to-Digital Converter ... Which is NOT yet supported on #NuttX OS ... Let's port the ADC HAL from BL602 MCU SDK

https://nuttx.apache.org/docs/latest/platforms/risc-v/bl602/index.html

We copied 3 C Source Files from #BL602 MCU SDK to #NuttX OS ... Plus a bunch of Header Files ... To make BL602 ADC work on NuttX

Some parts of #BL602 GLB HAL won't build nicely on #NuttX OS ... So we disable them out when compiling our ADC HAL
