m68knommu: move and fix the 68VZ328 platform bootlogo.h

The 68EZ328/bootlogo.h is not actually used in the 68EZ328 platform code
at all. It is used by the 68VZ328 platform code though, so move it to be
with the rest of the 68VZ328 platform code.

Commit 0ef7424765edca0180620c9e51727a5e5af111d4 ("fix broken boot logo
inclusion") modified the bootlogo code to not be included in asm code.
Modify 68VZ328/bootlogo.h so that the bootlogo bit map is named correctly
for direct use in the C code.
