aurel32 b7da58fd27 target-ppc: create a helper function to allow more flexible RAM allocation for PPC 4xx
The 4xx SDRAM controller supports a small number of banks, and each bank must
be one of a small set of sizes. The number of banks and the supported sizes
varies by SoC.

This function uses the user-specified RAM size to fill in the "ram_bases" and
"ram_sizes" arrays required by ppc4xx_sdram_init().
