SPIConfig.CS has a zero value of Pin(0) (GPIO0), but NoPin is Pin(0xff).
When the user does not set CS, the SPI driver sees Pin(0) != NoPin and
configures GPIO0 as the chip select output, hijacking whatever function
that pin was serving such as a button interrupt.
Default config.CS to NoPin when it is the zero value, so an omitted CS
field correctly means "no hardware CS pin". Applied to both ESP32-S3 and
ESP32-C3 SPI drivers.

This refactors and corrects the SPI implentation for the
ESP32C3 and ESP32S3 processors. There was a lot of duplicated
code, as well as some errors such as incorrectly calculating
speed on the esp32c3 implementation.
This will also be helpful when adding additional processors
that use very similar peripheral registers.

This updates lib/cmsis-svd, pulling in the updates to the Espressif SVD
files here:
https://github.com/cmsis-svd/cmsis-svd-data/pull/3
This is needed for wifi/BLE support on the ESP32-C3 (the older SVD files
were missing some necessary interrupts).
