Subject: chelsio: Use a more common const struct pci_device_id foo[] style
Chelsio code shares a pci_device_table from an #include file.
Make the include guard simpler and make the arrays const.
Reduces data by moving tables to text.
Removed unnecessary macros:
o CH_PCI_DEVICE_ID_TABLE_DEFINE_BEGIN
o CH_PCI_DEVICE_ID_TABLE_DEFINE_END
o CH_PCI_ID_TABLE_ENTRY (moved to the .h file)
Added new macro define:
o CH_PCI_ID_TABLE_ENTRY_DATA
text data bss dec hex filename
