Remove typedef for bool from eepro100.c

Remove typedef for bool from eepro100.c

eepro100.c shouldn't have the need to do this in its local header file.

And I recently started getting this:

$ make -j3
...
  CC    x86_64-softmmu/eepro100.o
/home/amit/src/qemu/hw/eepro100.c:112: error: two or more data types
in declaration specifiers
/home/amit/src/qemu/hw/eepro100.c:112: warning: useless type name in
empty declaration
make[1]: *** [eepro100.o] Error 1

so just remove the typedef and include <stdbool.h> instead.
