Fix esp_reset_reason_t constant names (#483)

The esp_reset_reason_t ESP_RST_PG and ESP_RST_CPU constant names don't
seem to exist. Instead, the actual names (added in esp-idf 5.2.2) are
ESP_RST_PWR_GLITCH and ESP_RST_CPU_LOCKUP.

The incorrect names caused the second-to-last match arm to be
interpreted as a binding name (that is, a catch-all), causing incorrect
behavior and build warnings when using esp-idf 5.2.2 and up.
