The default implementation of platform_maar_init is sufficient for Malta
boards where we want to allow speculation in the regions of memory
corresponding to DDR & disallow it elsewhere. Drop the custom
implementation such that the default is used, reducing the duplication
of information provided by the Malta platform code.
