I'd prefer this to be separate patches for 16 and 39 though.. Konrad

Both MSM8916 and MSM8939 have unnecessarily large reservations for the venus firmware for some reason. According to the ELF headers and downstream [1] 5 MiB is enough. Let's set the minimum size as default. With the dynamic reserved memory allocations boards can easily override this if needed, although in practice there does not seem to be any device with a different venus firmware size.
