esp32: Restore ESP32-C3 brownout detector settings to IDF defaults.
Commit a66bd7a48925d318e1dd6ada756df947ffacdc12 added the
ESP32_GENERIC_C3_USB board (now merged with ESP32_GENERIC_C3) and changed
the brownout detector from the default level 7 (~2.51V) to level 4
(~2.92V).
Raising the level again seems to fix random BOD resets on some of the
cheaper ESP32-C3 dev boards (that likely skimp on power supply
capacitance).
Specifically, this change prevents random resets running multi_bluetooth
tests on ESP32-C3 "SuperMini" board.
Also removed from the LOLIN_C3_MINI board as it seems this config is a copy
of the generic one.
This work was funded through GitHub Sponsors.
