Input: move input_bits_to_string() to input-compat.c
The input_bits_to_string() function has special handling for compat
tasks, formatting the output as a sequence of 32-bit hex values. To
better isolate compatibility-related code, move it from
drivers/input/input.c to drivers/input/input-compat.c.
No functional change intended.
