Move the LOAD_OFFSET definition from vmlinux.lds.S into system.h. On paravirtualized environments, it is necessary to detect the execution environment. One of the solutions is the multi entry point. The multi entry point allows a boot loader to start the kernel execution from the entry point which is different from the ELF entry point. The non standard entry point will defined as the specialized elf note which contains the LMA of the entry point symbol. The constant, LOAD_OFFSET, is necessary to calculate the symbol's LMA. Move the definition into the public header file to make it available to the multi entry point support.
