[csl-arm] Compiler warning removal for arm_pad_reg_upward, arm_handle_notshared_attribute

[Julian Brown <julian at codesourcery dot com>]

Hi,

This patch gets rid of build warnings for arm_pad_reg_upward (unused 
parameters) and arm_handle_notshared_attribute (sometimes defined but 
not used).

Tested by building with arm-none-eabi and arm-none-symbianelf 
(preprocessor conditional true for latter).

OK to apply?

ChangeLog:

  * config/arm/arm.c (arm_handle_notshared_attribute): Protect prototype
  and implementation with preprocessor conditional.
  (arm_pad_reg_upwards): Add ATTRIBUTE_UNUSED.
