When compile with CONFIG_FRAME_WARN=1024, there can be a warning:
drivers/i2c/i2c-core-base.c: In function ‘i2c_detect.isra’:
drivers/i2c/i2c-core-base.c:2507:1: warning: the frame size of 1028 bytes
is larger than 1024 bytes [-Wframe-larger-than=].
2507 | }
| ^
Mark i2c_detect_address() noinline_for_stack to avoid this warning.
