[PATCH] Fix 8139too ring size for dreamcast/embedded

Presently 2.6.6 backs out the CONFIG_8139_RXBUF_IDX in favor of using a
hardcoded 8139_RXBUF_IDX (again). This seems to have been done due to
some issues occuring with 8139_RXBUF_IDX =3D=3D 3, however (as the Kconfig
pointed out), we still need 8139_RXBUF_IDX =3D=3D 1 in the CONFIG_SH_DREAMC=
AST
case.

The patch which made this change can be seen at:

Before that, CONFIG_8139_RXBUF_IDX was set to 1 both in the
CONFIG_SH_DREAMCAST and CONFIG_EMBEDDED cases. This patch adds that
back into the current 8139too.
