Modified Files:
        src/sys/dev/pci: if_bge.c

Log Message:
Rework bge_reset() to more closely follow the Broadcom-supplied Linux driver:

1. Instead of enabling the buffer manager hardware-FSM only on
pre-5705 devices, initialize the buffer manager on all bge devices.
Modelled on the Broadcom-authored Linux driver.

2. Instead of enabling the memory arbiter hardware-FSM only on
pre-5705 devices, initialize the memory arbiter on all bge devices.
Modelled on the Broadcom-authored Linux driver.

3. Ditto the second copy of code which enables the memory arbiter.
Also, add an XXX asking, why taunt the chip this way a second time?
(The most plausible explanatoin is that enabling the memory arbiter
twice is my own darn fault, likely a cut-and-paste glitch I made many
moons ago, when re-ordering hardware enables to match the Linux drivers.)
