esp32: Extend support for S2 series, and S3 where applicable.
Improvements made: - PSRAM support for S2 - partition definition for 16MiB flash - correct ADC and DAC pins - correct GPIO and IRQ pins - S3 components in CMakeLists Based on original commit made by Seon Rozenblum aka @UnexpectedMaker. Signed-off-by: Damien George <[email protected]>
