[PATCH] S2io: modified loadable parameters

Attached is the patch to implement module loadable parameters as per new API.
Following is the list of changes.

1. Used new module_param() API.
2. List of variables for tx_fifo_len and rx_ring_sz replaced with array.
3. Some of the module parameters which can be set thru setpci command have
   been removed, such as latency_timer, max_read_byte_cnt, max_split_transactions.
4. Other parameters which were felt to be not required, such as rx_prio,
   tx_prio have been removed.
5. Interrupt moderation parameters(such as tx_urange_*) are no longer module
   loadable parameters since they can be configured thru' a separate patch
   available to customers.
6. Changed default max_read_byte_count to 1024.
7. If scatter-gather is enabled, checksum is enabled too.
8. Not verifying if module loadable parameters are within valid range
   (verify_load_param() removed).
