powerpc: keymile boards updates

- malloc size 4 MB for all keymile boards
- use generic FDT code for fixing up the DTS
- enable unit-led at startup for keymile boards
- remove some dts updates for keymile boards
- ppc_83xx, kmeter1: take FE/GbE PHYs out of reset
- ppc_83xx, kmeter1: change from Intel Strata to Spansion 64MB flash
  changed from Intel Strata to Spansion 64MB flash and changed flash layout.
