disas/microblaze: Add missing 'const' attributes
Making the opcode list 'const' saves memory. Some function arguments and local variables needed 'const', too. Add also 'static' to two local functions. Reviewed-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com> Signed-off-by: Stefan Weil <sw@weilnetz.de> [EI: Removed old prototypes to fix the build] Signed-off-by: Edgar E. Iglesias <edgar.iglesias@xilinx.com>
