4a410391cc ulp risc-v rtc i2c: Fix a bug where RTC I2C failed to initialize after esp_restart()
This commit fixes a bug wherein the RTC I2C peripheral got stuck after
the main CPU performs a soft reset by using esp_restart(). This is
because the RTC domain config registers for the RTC I2C domain are not
cleared after the soft restart and hence need to be cleared manually
while initializing the RTC I2C peripheral again.

Closes https://github.com/espressif/esp-idf/issues/10468

4fde033a5f ulp: Added support for RTC I2C driver for ULP RISC-V on esp32s2 and esp32s3
This commit adds support for using the RTC I2C peripheral on the ULP
RISC-V core for esp32s2 and esp32s3. It also adds an example to demonstrate the
usage of the RTC I2C peripheral.

This commit also modifies the rtc_i2c register structure files to enable
the use of bitfields in the ULP RISC-V RTC I2C driver.
