Subject: [PATCH 1/3] staging: r8188eu: set firmware path in a macro

The r8188eu driver requires a firmware file, the path of which was
hardcoded as constant strings in two places:
(1) in core/rtw_fw.c, in function load_firmware(),
(2) in os_dep/os_intfs.c, in the MODULE_FIRMWARE() call.

Declare the path using a macro, FW_RTL8188EU, and replace the above
constant strings with the macro. That's the way it is done in many other
drivers. The new macro is defined in include/drv_types.h, because that
file is already included by both of the above files (or at least their
headers) and because it already contains other driver constants, like
its name and version.
