This reverts commit ceaf959678.
The AMD Picasso SoC doesn't support x2APIC and neither advertises the
presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the
bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID
leaves, so just checking for the presence of that CPUID leaf isn't
sufficient to be sure that EDX of the CPUID leaf 0xb will contain a
valid APIC ID.
In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores
which causes coreboot to get stuck somewhere at the end of MP init.
I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID
function 1 is set instead of adding back the is_x2apic_mode check.
TEST=Mandolin with a Picasso SoC boots again.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper

called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.
This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs

printk to mp_init_with_smm. For this the original mp_init_with_smm
function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.

printing a message, also add a comment at the mp_init_with_smm call

Using cb_err as return type of mp_run_on_aps, mp_run_on_all_aps,
mp_run_on_all_cpus and mp_park_aps clarifies the meaning of the
different return values. This patch also adds the types.h include that
provides the definition of the cb_err enum and checks the return value
of all 4 functions listed above against the enum values instead of
either checking if it's non-zero or less than zero to handle the error
case.

Some elements in the ACPI CPPC table allow static DWORDs. Instead of
using a fake register resource, use a tagged union with the two types
"register" and "DWORD" and respective macros for CPPC table entries.
Test: dumped SSDT before and after do not differ.

Using cb_err as return type clarifies the meaning of the different
return values. To not change the return types of mp_run_on_aps which is
exposed outside of this compilation unit to keep the scope of this patch
limited, the return value of run_ap_work gets translated to the int
values in mp_run_on_aps. This could also be done by a cast of the
run_ap_work return value to int, but an explicit translation of the
return values should be clearer about what it does there.
