RTC_CNTL_REG not recognized

[arjanmels]

The RTC_CNTL_REG (https://github.com/espressif/esp-idf/blob/6330b3345e87eb4401e7be7c8b6fea2870c35d9f/components/soc/soc/esp32/include/soc/rtc_cntl_reg.h#L1074) is not properly recognized. All its fields are attached to the previous register: RTC_CNTL_BIAS_CONF_REG.

This is probably because the register has "no name": the name consistst of the peripheral prefix "RTC_CNTL_" and the register prefix "REG".

For the moment I will work around by doing a patch to add the RTC_CNTL_REG, but I cannot remove the fields from RTC_CNTL_BIAS_CONF_REG in this way.
