arm: plat-orion: introduce PLAT_ORION_LEGACY hidden config option
Until now, the PLAT_ORION configuration option was common to all the Marvell EBU SoCs, and selecting this option had the effect of enabling the MPP code, GPIO code, address decoding and PCIe code from plat-orion, as well as providing access to driver-specific header files from plat-orion/include. However, the Armada 370 and XP SoCs will not use the MPP and GPIO code (instead some proper pinctrl and gpio drivers are in preparation), and generally, we want to move away from plat-orion and instead have everything in mach-mvebu. That said, in the mean time, we want to leverage the driver-specific headers as well as the address decoding code, so we introduce PLAT_ORION_LEGACY. The older Marvell SoCs need to select PLAT_ORION_LEGACY, while the newer Marvell SoCs need to select PLAT_ORION. Of course, when PLAT_ORION_LEGACY is selected, it automatically selects PLAT_ORION. Then, with just PLAT_ORION, you have the address decoding code plus the driver-specific headers. If you add PLAT_ORION_LEGACY to this, you gain the old MPP, GPIO and PCIe code. Again, this is only a temporary solution until we make all Marvell EBU platforms converge into the mach-mvebu directory. This solution avoids duplicating the existing address decoding code into mach-mvebu.
