Compilation issue with -Wformat= as used by esp32_arduino core

[mazgch]

Subject of the issue

Install arduino_esp32 version 3.0.0

Your workbench

Arduino IDE 2.3.2 with warnings enabled (Compiler Warnings set to ALL in Arduino IDE->Settings)

Steps to reproduce

Compile with warnings enabled (Compiler Warnings set to ALL in Arduino IDE->Settings)

Expected behaviour

Compiler should not create warnings for printfs or Scafs regrind type mismatches with uint32_t or int32_t types.

Actual behaviour
