amdfwtool: Upgrade "relative address" to four address modes
Address Mode 0: Physical Address, bit 63~56: 0x00 Address Mode 1: Relative Address to entire BIOS image, bit 63~56: 0x40 Address Mode 2: Relative Address to PSP/BIOS directory, bit 63~56: 0x80 Address Mode 3: Relative Address to slot N, bit 63~56: 0xC0 It is the expanding mode for simple relative address mode, for which address_mode equals 1. Only mode 2 is added. We need to record current table base address and calculate the offset. The ctx.current_table is zero outside the table. When it goes into the function to integrate the table, it should backup the old value and get current table base. Before it goes out the function, it should restore the value. If the table address mode is 2, the address in each entry should be also add address mode information. If not, the address mode in entry is meanless. The old mode 0,1 should be back compatible.
