Two of the MCT data structures passed as substructures to ramstage were
not packed, and additionally no alignment was specified. On at least
SP5100-based platforms, specifying packed with no alignment caused boot
failure dependent on the exact compiled binary layout (LPC hang).
Specifying the alignment and packing the remaining structures appears to
have resolved the remaining LPC hang issues on the KGPE-D16. Note that
packing the remaining structures alone was not sufficient to eliminate
the hang, however removing the packed attribute entirely (during debugging)
did resolve the hang at the expense of potential problems in ramstage.

Our EDID code had always been aligning the framebuffer's
bytes_per_line (and x_resolution dependent on that) to 64. It turns out
that this is a controller-dependent parameter that seems to only really
be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper
function to calculate bits-per-pixel dependent values) probably actually
broke this for some other controllers by applying the alignment too
widely.
This patch makes it explicitly configurable and depends the default on
ARCH_X86 (which seems to be the simplest and least intrusive way to make
it fit most cases for now... boards where this doesn't apply can still
override it manually by calling edid_set_framebuffer_bits_per_pixel()
again).
