microblaze: Kernel parameters should be parsed earlier
Kernel command line should be parsed before cma initialization to be able
to get cma sizes from command line. That's why call parse_early_param()
before dma_continugous_reserve().
Unfortunately it can't be called earlier in machine_early_init() because
if earlycon is passed in the command line the parse_early_param() attempts
an ioremap which fails as the memory params are not set yet.
