Add support for x86_64 bootblock on qemu.
Introduce a new approach to long mode support. The previous patch set
generated page tables at runtime and placed them in heap. The new
approach places the page tables in memory mapped ROM.
Introduce a new tool called pgtblgen that creates x86 long mode compatible
page tables and writes those to a file. The file is included into the CBFS
and placed at a predefined offset.
Add assembly code to load the page tables, based on a Kconfig symbol and
enter long in bootblock.
The code can be easily ported to real hardware bootblock.
Tested on qemu q35.

Some mainboards with an ASPEED BMC do the serial routing setup in the
BMC boot phase on cold boot. This results in scrambled console output
when this is not finished fast enough.
This adds a delay of 500ms as workaround in the BMCs uart setup that
can be selected at mainboard level.
A user may disable the workaround when using another BMC firmware like
OpenBMC, u-bmc or some custom BMC bootloader with fast serial setup.

Currently all stages that need cbmem need an implementation of a
cbmem_top function. On FSP and AGESA platforms this proves to be
painful and a pointer to the top of lower memory if often passed via
lower memory (e.g. EBDA) or via a PCI scratchpad register.
The problem with writing to lower memory is that also need to be
written on S3 as one cannot assume it to be still there. Writing
things on S3 is always a fragile thing to do.
A very generic solution is to pass cbmem_top via the program argument.
It should be possible to implement this solution on every
architecture.
Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.
