[PATCH 1/2] scripts/gdb: mm: Cast untyped symbols in x86_page_ops

The symbols phys_base, _text, and _end, used in x86_page_ops are either
defined in assembly or implicitly by the linker. Thus, they lack type
information and cause a conversion error after gdb.parse_and_eval.
Explicitly cast these expressions to unsigned long.
