[PATCH v1 1/1] x86/of: Remove unused early_init_dt_add_memory_arch()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Recently the objtool starts complaining on the dead code
in the object files, in particular

vmlinux.o: warning: objtool: early_init_dt_scan_memory+0x191: unreachable instruction

when CONFIG_OF=y.

Indeed, the entire early_init_dt_scan() is not used on x86 and making it
compile (with help of CONFIG_OF) will abrupt the code flow since in the
middle of it we have a BUG() instruction.

Remove the entire culprit function to make objtool happy.
