util/ifdtool: Add support for checking GPR0 status
This patch adds support for the new command-line option `-c` to
the ifdtool, which is able to check GPR0 (Global Protected Range)
status.
This patch also add helper function get_enabled_gprd() to get enabled
GPR0 settings. It used in enable_gpr0() and is_gpr0_protected().
Developers can use ifdtool with '-c' option to check whether GPR0 is
set to enabled or disabled in the binary file.
