treewide: Add Kconfig variable MEMLAYOUT_LD_FILE
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.
