Provide a p4 ESP-IDF 5.5.x bootloader compatible with p4 chip rev < 3.0

Basically, a bootloader compiled with 
```
CONFIG_ESP32P4_SELECTS_REV_LESS_V3=y
CONFIG_ESP32P4_REV_MIN_100=y
```

This bootloader should be flashed instead of the current v3.0 one, if a chip with rev < 3.0 is detected.

## Motivations

As per the "root cause analysis" in the description of [this issue](https://github.com/esp-rs/esp-idf-sys/issues/376).
