Several improvements * Drop the detection of EFI through kallsyms. This detection is no longer useful since commit2c0c4c9fd1("Using CONFIG_EFI instead of user defined HAS_EFI (#1036)") replaced `HAS_EFI` with `CONFIG_EFI`. * Use `...-objs-y` and `...-objs-$(CONFIG_...)` logic to choose which `cpu.asm` file is being built. This is something that other modules do in Linux kernel source. * Introduce `quiet_cmd_...` and `cmd_...` definition in order to use the build system of the kernel to compile `cpu.asm` with NASM. This should prevent issues like the one mentioned in2210002bab("Fixed build error on latest Ubuntu") from happening again. Moreover this makes the custom clean command `rm -f ${asm-path}/cpu.o` no longer necessary. * Remove variables which become unused after these changes. Now, all that `Makefile` needs is a kernel directory, specified with `KSRC`. This change has been tested on a test system running Ubuntu 20.10 and on GitHub Actions workers running Ubuntu 16.04, 18.04 and 20.04 on Linux 5.4.0-1040-azure. It has also been compile-tested on many other Linux distributions using a work-in-progress GitHub Actions configuration (https://github.com/fishilico/chipsec/actions/runs/661200380).
