Feature/esp spi bitbang

[eren-terzioglu]

Summary

Bitbang device supports are added due to flexibility on device testing and other use cases especially the devices which has one related peripheral (e.g. There is one SPI peripheral for C3 or there is one I2C peripheral for C6). This feature adds another interface for related peripheral in cases of when number of peripherals are not enough.

One of the example use case is: Implementation used through working on SPI Slave on device testing on devices which has one SPI peripheral (e.g. esp32c3, esp32c6). With Bitbang support it became possible to test slave driver without needing other chip who acts as master.

• esp32[s2|s3]: Add SPI bitbang support
• esp32[c3|c6|h2]: Add SPI bitbang support

Impact

ESP32, ESP32S2, ESP32S3, ESP32C3, ESP32C6, ESP32H2

Testing

Configurations used with ESPRESSIF_SPI_BITBANG option enabled additionally:

esp32s3-devkit:spi
esp32c3-generic:spi
esp32c6-devkitc:spi

Default MOSI-MISO(GPIO3-GPIO2) pins connected with a wire and this command applied:

nsh> spi exch AD
Sending:	AD 
Received:	AD 
nsh> spi exch AB
Sending:	AB 
Received:	AB

@lupyuen do you have some idea about this error:

Seems error is unrelated to this PR, we can fix it in other PR.

@eren-terzioglu Yep let's wait for the Red Error Boxes below to disappear from nuttx-dashboard.org. Then we can rebase with master.

Meanwhile I cloned your fork to my repo, enabled all the builds, to check if there are other errors: https://github.com/nuttxpr2/nuttx/actions/runs/11701148540
