linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>
<linux/kconfig.h> is included from all the kernel-space source files, including C, assembly, linker scripts. It is intended to contain a minimal set of macros to evaluate CONFIG options. IF_ENABLED() is an intruder here because (x ? y : z) is C code, which should not be included from assembly files or linker scripts. Also, <linux/kconfig.h> is no longer self-contained because NULL is defined in <linux/stddef.h>. Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF() takes the general boolean expression instead of a CONFIG option so that it fits better in <linux/kernel.h>.
