The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc`
is included from platform (CPU/SoC) code and the `UDELAY_TSC` Kconfig
option is enabled.
Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and
drop the now-redundant inclusions from platform code. Also, deduplicate
the `UDELAY_TSC` guards.

IDS (Integrated Debug Services) options are meant to be enabled when one
wants to debug AGESA. Since they are compile-time options, using Kconfig
is the logical choice. Currently, none of the options builds.
Tested with BUILD_TIMELESS=1 without adding the configuration options
into the binary, and Asus A88XM-E does not change.

Since current AMD SoCs don't need some wait time between INIT and SIPI,
we can skip the 10ms wait there, which improves the boot time a bit.
before: CPU_CLUSTER: 0 init finished in 632 msecs
after: CPU_CLUSTER: 0 init finished in 619 msecs
mpinit still works on Mandolin and all CPU cores show up and are usable.
This also doesn't change the binary in a timeless build for boards/SoCs
that don't select X86_AMD_INIT_SIPI which I verified for lenovo/x230.

The alignment for `struct cpu_info` is wrong on x86_64. c_start.S uses
the `push` instruction when setting up the cpu_info struct. This
instruction will push 8 bytes but `unsigned int` is 4 bytes. By making
it a `size_t` we get the correct size for both x86_32 and x86_64.

Commit 1aa60a95bd broke microcode loading for chipsets that have a
microcode blob with a total_size field set to 0. This appears to be
support for older chipsets, where the size was set to 0 and assumed to
be 2048 bytes. The fix is to change the result of the subtraction to a
signed type, and ensure the following comparison is done without
promoting the signed type to an unsigned one.

This fixes a hard to debug hang that could occur in any stage, but in
the end it follows simple rules and is easy to fix.
In long mode the 32bit displacement addressing used on 'mov' and 'lea'
instructions is sign-extended. Those instructions can be found using
readelf on the stage and searching for relocation type R_X86_64_32S.
The sign extension is no issue when either running in protected mode or
the code module and thus the address is below 2GiB. If the address is
greater than 2GiB, as usually the case for code in TSEG, the higher
address bits [64:32] are all set to 1 and the effective address is
pointing to memory not paged. Accessing this memory will cause a page
fault, which isn't handled either.
To prevent such problems
- disable R_AMD64_32S relocations in rmodtool
- add comment explaining why it's not allowed
- use the pseudo op movabs, which doesn't use 32bit displacement addressing
- Print a useful error message if such a reloc is present in the code
Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

Allows compile-time optimisation on platforms that do not wish
to enable runtime checking of X2APIC.
Legacy lapic_cpu_init() is incompatible so there is dependency
on PARALLEL_MP. Also stop_this_cpu() is incompatible, so there
is dependency on !AP_IN_SIPI_WAIT.
Since the code actually lacks enablement of X2APIC (apparently
assuming the blob has done it) and the other small flaws pointed
out in earlier reviews, X2APIC_RUNTIME is not selected per
default on any platform yet.
