net/ehea: bitops work on unsigned longs

The flags field of struct ehea_port is only used with test_bit(),
clear_bit() and set_bit() and these interfaces only work on
"unsigned long"s, so change the field to be an "unsigned long".  Also,
this field only has two bits defined for it (0 and 1) so will still be
fine if someone builds this driver for a 32 bit arch (at least as far as
this flags field is concerned).

Also note that ehea_driver_flags is only used in ehca_main.c, so make it
static in there.
