tools: mkimage: Ensure munmap unmaps the same length that was mapped
The set_header call in kwbimage.c adds a checksum to the end of the
image in addition to setting up the header. It 'helpfully' updates the
st_size to match the fact that the file is now longer. However, mkimage
uses this length in the munmap call. This can lead to unmapping an extra
page, of perhaps required data. When this happens, a SEGV can occur.
To prevent this from happening, the munmap call now uses the same length
that was passed to mmap. This could also have been fixed by not changing
the length in kwbimage.c, however changing it in the main file means
that other plugins will also not fall for the same trap.

Make kmalloc'ed memory really DMA-safe
In Linux, the memory returned by kmalloc() is DMA-capable.
However, it is not true in U-Boot.
At a glance, kmalloc() in U-Boot returns address aligned with
ARCH_DMA_MINALIGN. However, it never pads the allocated memory.
This half-way house is completely useless because calling kmalloc()
