[PATCH] S2io: Support for Xframe II NIC

Hi,
This patch provides basic support for the Xframe II adapter.
Includes the following changes:
1. New values to program XAUI interface.
2. Print the PCI/PCI-X mode(bus frequency, width).
3. Remove EOI from reset during intialization.
4. Enable all 8 PCCs if Xframe II adapter.
5. Programs the RLDRAM size depending on the device.
(Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb).
6. Enable extended(64-bit) statistics counters.
7. Program timer interrupt duration based on PCI/PCI-X clock speed.
8. Not required to save/restore PCI config space before/after reset.
