ARC: [plat-sim] unbork non default CONFIG_LINUX_LINK_BASE
HIGHMEM support bumped the default memory size for nsim platform to 1G. Thus total memory ended at the very edge of start of peripherals address space. With linux link base shifted, memory started bleeding into peripheral space which caused early boot bad_page spew !
