099f648686 ulp-riscv: ULP RISC-V I2C example gets stuck on esp32s2
This commit fixes an issue where in the ULP RISC-V I2C example causes
a spurious wakeup of the main CPU because of a Trap signal when the ULP
core does not meet the wakeup threshold values. This was due to the fact
that the RTC_CNTL_COCPU_DONE signal was being set before the
RTC_CNTL_COCPU_SHUT_RESET_EN signal which was causing the the ULP RISC-V
core to not reset properly on each cycle.

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.
