ARM: 5904/1: ARM: Always generate the IT instruction when compiling for Thumb-2

Current behaviour is to generate the IT instruction only for Thumb-2
code. However, the kernel helpers in entry-armv.S are compiled to ARM in
a unified syntax file (if THUMB2_KERNEL). Recent compilers warn about
missing IT instruction in unified assembly syntax files. The patch
changes the "-mimplicit-it" gas option to "always".
