An unidentified combination of speculative reads and branch
predictions inside WRPROT-cacheable memory can cause invalidation of
cachelines and loss of stack on models based on NetBurst
microarchitecture.
Therefore disable WRPROT region entirely for all family F models.
As an extreme example, just changing the location of a constant string
passed to printk() has been witnessed to make a the boot fail early on
in romstage.

Remove locking of PCI device 00:00.0 registers (nehalem/finalize.c)
and remove setting the zeroth bit of the MSR_LT_LOCK_MEMORY = 0x2e7 MSR
register (model_2065x/finalize.c) to fix a frozen boot and S3 resume issue
which became apparent with commit d533b16669.
More detailed, either setting the LSB of the 32 bit register at 0x98
of the PCI device 00:00.0 (in the intel_nehalem_finalize_smm function) or
setting the LSB of the the MSR register MSR_LT_LOCK_MEMORY = 0x2e7 (in the
intel_model_2065x_finalize_smm function) indepentenly causes a freeze
during bootup or a complete session loss on resuming from S3 as described
here: https://mail.coreboot.org/pipermail/coreboot/2018-April/086564.html
It seems like Nehalem CPUs do not have a MSR_LT_LOCK_MEMORY register.
Additionally, the "Intel Core i7-600, i5-500, i5-400 and i3-300 Mobile
Processor Series, Datasheet Volume Two" indicates that registers of the
PCI device 00:00.0 cannot be locked manually. Instead, they can only be
locked by TXT, VT-d, CMD.LOCK.MEMCONFIG, ME_SM_LOCK or D_LCK.
Finally, the addresses and sizes of these registers were partially wrong.
Tested on Lenovo X201i with a Core i3 330M (no AES-NI, no VT-d and no TXT
support compared to the Core i5 and Core i7 processors of a X201).
