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. Closes #10301
