hexagon: uaccess: remove clear_user_hexagon()

Patch series "hexagon: Fix up instances of -Wmissing-prototypes".

This series fixes all the instances of -Wmissing-prototypes in
arch/hexagon, as it is about to be enabled globally in a default build.

This patch (of 19):

Clang warns:

  arch/hexagon/mm/uaccess.c:39:15: warning: no previous prototype for function 'clear_user_hexagon' [-Wmissing-prototypes]
     39 | unsigned long clear_user_hexagon(void __user *dest, unsigned long count)
        |               ^
  arch/hexagon/mm/uaccess.c:39:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
     39 | unsigned long clear_user_hexagon(void __user *dest, unsigned long count)
        | ^
        | static
  1 warning generated.

This function appears to have been unused since it was introduced in
commit 7567746e1c0d ("Hexagon: Add user access functions"), so remove it.
