ppc4xx_sdram: Get rid of the init RAM hack

Browse source 
The do_init parameter of ppc4xx_sdram_init() is used to map memory
regions that is normally done by the firmware by programming the SDRAM
controller. Do this from board code emulating what firmware would do
when booting a kernel directly from -kernel without a firmware so we
can get rid of this do_init hack.
