meta-asrock:e3c246d4i:kernel: shrink image size

During the migration to Linux kernel 6.12, the e3c246d4i platform
began encountering flash image size overflows due to increased
kernel size.

'''
  ERROR: obmc-phosphor-image-1.0-r0 do_generate_static:
   Image '/target/e3c246d4i/build/deploy/images/e3c246d4i/fitImage-obmc-phosphor-initramfs-e3c246d4i-e3c246d4i' is 52292 bytes too large!

To address this, the following debug options have been disabled:

 - CONFIG_FUNCTION_TRACER:
   Enables function-level instrumentation for tracing via ftrace.
   Disabling it significantly reduces kernel image size.

   Side effect: Removes support for function call tracing and
   performance profiling using ftrace.

 - CONFIG_DEBUG_LIST:
   Adds runtime checks for kernel linked list misuse.
   Disabling it reduces code size and runtime overhead.

   Side effect: Disables automatic detection of list corruption
   (e.g., double insertions or invalid deletions), which may make
   certain memory bugs harder to detect.

These changes help reduce the kernel image size while retaining
essential debugging capabilities like dynamic debug and symbol-based
crash analysis.
