[POWERPC] Small fixes for the Ebony device tree
This patch corrects a number of minor errors in the Ebony device tree: - Missing (given as 0) cache sizes are added to the CPU node - device_type properties are removed from nodes which don't have a reasonably well defined device_type binding. This does require a very small code change to locate the busses to be probed for of_platform devices by 'compatible' instead of 'device_type'. - A node is added for the SRAM controller - The unit address of the small-flash node is adjusted to correctly reflect the reg property. - device_type values for the MAL and ZMII are updated to reflected more up-to-date versions of the binding. - An incorrect offset in the partition map for the large-flash node is corrected. - Some redundant values, already commented out are removed entirely.
