Except for family15, all AGESA boards have moved
away from AGESA_LEGACY_WRAPPER, thus they all
have POSTCAR_STAGE now.
AGESA family15 boards remain at AGESA_LEGACY=y, but
those boards have per-board romstage.c files and
are not touched here.

Move all boards that have moved away from AGESA_LEGACY_WRAPPER
or BINARYPI_LEGACY_WRAPPER to use POSTCAR_STAGE.
We use POSTCAR_STAGE as a conditional in CAR teardown to tell
our MTRR setup is prepared such that invalidation without
writeback is a valid operation.

A decision has been made that boards with LATE_CBMEM_INIT
will be dropped from coreboot master starting with next
release scheduled for October 2017.
As existing implementation of CAR teardown in AGESA can only
do either EARLY_CBMEM_INIT or ACPI S3 support, choose the former.
ACPI S3 support may be brought back at a later date for
these platforms but that requires fair amount of work fixing
the MTRR issues causing low-memory corruptions.

Change register preservations and fix comments about register
usage accordingly. Do this to avoid use of %mm0-2 registers inside
macros defined in gcccar.inc, as future implementation of
C_BOOTBLOCK_ENVIRONMENT will use them as well.
Adjust caller side accordingly.

After modifications:
f12 and f14 are identical
f10 is f14 with invd -> wbinvd modification added to HOOK_F10
f15 is f10 with invd -> wbinvd modification added to HOOK_F15
f15tn is f15 modified to use with TN / KV / KM

A comparison with a two's complement in gcccar.inc has dubious
GAS/AT&T notation. Clang miss-parses 0x-1 as an invalid hexadecimal

AGESA code has wrong definition of CR0_PE bit (1 instead of 0).
PE [Protected Mode Enable] is 0 bit in CR0 register
(If PE=1, system is in protected mode, else system is in real mode)
Bit 1 is MP [Monitor co-processor]
(Controls interaction of WAIT/FWAIT instructions with TS flag in CR0)
System uses CR0_PE define, but I didn't expect any consequences because of this bug.

_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)
specified in the ECX register into registers EDX:EAX.
The EDX register is loaded with the high-order 32 bits of the MSR
and the EAX register is loaded with the low-order 32 bits.
EDX:EAX = MSR[ECX]
So bit 49 will be contained in EDX register.
Buggy code instead of bit 49 (CombineCr0Cd) sets bit [49-32=17] (PfcStrideDis).
PfcStrideDis bit disables stride prefetch generation. This leads to memory
bandwidth loss.

Supermicro H8QGI board
After applying this change i observed huge memory bandwidth increase in tests
that runs on small amount of cores. But unfortunately it doesn't affect
overall bandwidth results on 4P system with 48 cores.
So i think that in this system leading limiting factor is
AMD HT-ASSIST feature (Probe filter).
But right now it is not working. System stucks in Linux boot. I have done
some experiments and figured out that stuck happens when system have cores in
compute unit (CU) other than CU with BSC (boot strap core).
CU is two cores (primary and seconary) that shares some things (L2 cache, FPU ...)
So with probe filter i can boot Linux with one (BSC)
or two (BSC + secondary core in its CU) cores.
And with this configuration i can see memory bandwidth on 1 core (or two cores)
close to original bios.
