ESP32-D0WD-V3 does not enter deep sleep with 2.x.x library #7510
Description
Board
OLIMEX-ESP32-DevKit-LiPo
Device Description
The board is OLIMEX-ESP32-DevKit-LiPo and has ESP32-WROOM-32E module which esptool reports as ESP32-D0WD-V3.
Hardware Configuration
No additional HW attached to the pins
Version
v2.0.5
IDE Name
Arduino 1.8.19
Operating System
Ubuntu 20.04
Flash frequency
40Mhz
PSRAM enabled
no
Upload speed
115200
Description
If Touch wake is used, the processor will not enter deep sleep and will reboot continuously.
The problem is happening with version all versions of Arduino library from 2.0.0 to 2.0.5.
The problem does not occur with version 1.0.6 of the Arduino library.

Other Steps to Reproduce
I can reproduce the same issue with ESP32-PICO-V3 and library 2.0.5
Interesting is that with a board having module ESP32-WROOM-32 (reported by esptool as ESP32-D0WDQ6 Rev1) the issue does not reproduce.
