ifdtool: fix flumap handling in chipsets prior ibex peak/5 series
The Upper Map section in the descriptor contains a database of flash
chips (VSCC Table). Its offset is located at a fixed offset from
the beginning of the image. ifdtool falsely calculates the offset
from the descriptor signature which has moved by 16 bytes with
step b of the Ibex Peak (5 series) chipset. This produces bogus
output for all chipsets older than that.
This patch corrects the behavior by calculating the offset of
flumap by adding 4096 - 256 - 4 to the start of the image.
