ARM: 7068/1: process: change from __backtrace to dump_stack in show_regs
Currently, show_regs calls __backtrace which does nothing if CONFIG_FRAME_POINTER is not set. Switch to dump_stack which handles both CONFIG_FRAME_POINTER and CONFIG_ARM_UNWIND correctly. __backtrace is now superseded by dump_stack in general and show_regs was the last caller so remove __backtrace as well.
