intel/lynxpoint: Make inclusion of Intel ME optional
Current build configuration always wants to include an Intel Management Engine
(ME) firmware (`me.bin`) on Intel Lynx Point systems. However, we can have a
working coreboot without it, as long as the factory delivered ME firmware is
kept untouched in the flash ROM. So let the user decide if a ME firmware will
be included in the build by introducing the Kconfig option `HAVE_ME_BIN`.
The same was done in commit 99fd30e4 (sandybridge: Make inclusion of me.bin
optional) [1] for Intel Sandy Bridge (BD82x6x).
