Problem is that now smbios code from dell-laptop.c is moved into
dell-smbios.c and dell-smbios.h and LED subsystem starts using
dell-smbios.h. In this case I'm thinking that we have something like API
usable by other modules/subsystem. And I'm thinking if it is not better
to create "correct" API now instead rewriting code in LED and platform
subsystem again later... As this API needs to provide just 1 function,
send command to Dell SMBIOS I think that API is still minimal. Currently
we have another two functions alloc/free buffer (needed for send).
