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.
