bna: Brocade 1860 IOC PLL, Reg Defs and ASIC Mode Changes 

Add logic to set ASIC specfic interface in IOC, HW interface initialization
APIs, mode based initialization and MSI-X resource allocation for 1860 with
no asic block. Add new h/w specific register definitions and setup registers
used by IOC logic.

Use normal kernel declaration style, c99 initializers and const for mailbox
structures. Remove unneeded parentheses.
