a common file shared between 83xx & 85xx platforms that have QE's.

This patch extends the number of supported UECs to 4. Note that the
problem of QE thread resources exhaustion is resolved by setting the
correct number of QE threads according to Ethernet type (GBE or FE).

Change return values of init() functions in all Ethernet drivers to conform
to the following:
>=0: Success
<0: Failure
All drivers going forward should return 0 on success. Current drivers that
return 1 on success were left as-is to minimize changes.

Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it. Add function qe_upload_firmware() to parse the blob and
perform the actual upload. Add command-line command "qe fw" to take a firmware
blob in memory and upload it. Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware. Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

Actually, fixed a large bug in the UEC for *all* platforms.
How did this ever work?
uec_init() did not follow the spec for eth_init(), and returned
0 on success. Switch it to return the link like tsec_init()
(and 0 on error)
The immap for the 8568 was defined based on MPC8568, rather than
CONFIG_MPC8568
CONFIG_QE was off
CONFIG_ETHPRIME was set to "Freescale GETH". Now is "FSL UEC0"
Fixed a comment about the ranges for CONFIG_ETHPRIME if TSEC_ENET is
enabled

The problem is not gcc4 but the code itself. The BD_STATUS() macro can't
be used for busy-waiting since it strips the 'volatile' property from
the bd variable. gcc3 was working by pure luck.
This is a follow on patch to "Fix the UEC driver bug of QE"
The patch prevents the GCC tool chain from striping useful code for
optimization. It will make UEC ethernet driver workable, Otherwise the
UEC will fail in tx when you are using gcc4.x. but the driver can work
when using gcc3.4.3.
