GRETH driver updated, 10-15% performance improvements for GBIT MAC,
unnecessary RX interrupts not taken which under heavy load saves approx.
1500 interrupts/s, one task removed saving about 5kb memory and 1 bug
solved.
BUG: RX interrupt was enabled before the RX-daemon was created which could
result in a faulty call to rtems_event_send.

Deadlock may arise when the EDCL bug link is used to tunnel
console output over Ethernet, when Ethernet is down one should
avoid using console (only during debugging of LEON targets)

The previous code only checked if d-cache snooping was implemented,
however snooping may be available but not enabled which may lead
to driver bugs.

All LEON3/4 systems have a CPU-id, if on a single-CPU system the
ID is always zero. On a multicore system it ranges from 0 to 15.
The CPU index should always by updated even in a non-MP RTEMS OS
since the CPU running RTEMS may not always be CPU0. For example
when RTEMS runs on CPU1 and Linux on CPU0 in a mixed ASMP system.
The old code executed within the IRQ controller initialization code
makes no sense since the ASR register is a CPU register, it has
nothing to do with AMBA initialization either.

The SHM code always wakes one CPU more that configured, however
this has never been a problem since RTEMS will be running on all CPUs
or only two cores were available.
