util_macros.h: have array pointer point to array of constants
Using the new find_closest() macro can result in the following sparse
warnings.
drivers/hwmon/lm85.c:194:16: warning:
incorrect type in initializer (different modifiers)
drivers/hwmon/lm85.c:194:16: expected int *__fc_a
drivers/hwmon/lm85.c:194:16: got int static const [toplevel] *<noident>
drivers/hwmon/lm85.c:210:16: warning:
incorrect type in initializer (different modifiers)
drivers/hwmon/lm85.c:210:16: expected int *__fc_a
drivers/hwmon/lm85.c:210:16: got int const *map
This is because the array passed to find_closest() will typically be
declared as array of constants, but the macro declares a non-constant
pointer to it.
