LoongArch: Remove some extern variables in source files

There are declarations of the variable "eentry", "pcpu_handlers[]" and
"exception_handlers[]" in asm/setup.h, the source files already include
this header file directly or indirectly, so no need to declare them in
the source files, just remove the code.
