Extend find_data_type_die() to find data type from PC-relative address using die_find_variable_by_addr(). Users need to pass the address for the (global) variable. The offset for the variable should be updated after finding the type because the offset in the instruction is just to calcuate the address for the variable. So it changed to pass a pointer to offset and renamed it to 'poffset'. First it searches variables in the CU DIE as it's likely that the global variables are defined in the file level. And then it iterates the scope DIEs to find a local (static) variable.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
