There are MSRs that are programmable per-core not per-thread, so add
a function to check whether current executing CPU is a primary core
or a "hyperthreaded"/secondary core. For instance when trying to
program Core PRMRR MSRs(per-core) with mp_init, cpu exception is thrown
from the secondary thread. This function was used to avoid that.
Potentially this function can be put to common code or arch/x86 or cpu/x86.

Some variants need the internal pull resistor on GPIO_SSUS_40
set explicitly to pull down rather than disabling the pull,
in order for the ram-id to be read correctly via GPIO.
Correct this by adding a function to enable and set the internal pull

build and boot issue with this change.
Besides that, rename the romstage_after_verstage to romstage_c_entry

Baytrail SoC has a bug where in some cases the DisplayPort can hang
leading to a non-working display (it just stays black). To avoid this
hang, a patch was introduced in 02/2016
(1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort)
but per default not switched on so that each
mainboard can decide if it wants to use this patch or not.
Recently a new case of this bug was reported by Benoit Sansoni
(benoit.sansoni@kontron.com) and he requested to enable this fix per
default as it costs him a lot of time to find the cause and even the
already available fix in coreboot. To avoid this effort for someone
else in the future we can enable this fix per default as no negative
side effects are known and it is now tested at Siemens and at
Kontron on different mainboards with success.
As the goal is to enable this code permanently the config switch is not
longer needed and is removed.

SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with
the ability to perform tx and rx of flash command and response at the
same time. Instead of introducing this notion at SPI flash driver layer,
clean up the interface to SPI used by flash.
Flash uses a command-response kind of communication. Thus, even though
SPI is duplex, flash command needs to be sent out on SPI bus and then
flash response should be received on the bus. Some specialized x86
flash controllers are capable of handling command and response in a
single transaction.
In order to support all the varied cases:
1. Add spi_xfer_vector that takes as input a vector of SPI operations
and calls back into SPI controller driver to process these operations.
2. In order to accomodate flash command-response model, use two vectors
while calling into spi_xfer_vector -- one with dout set to
non-NULL(command) and other with din set to non-NULL(response).
3. For specialized SPI flash controllers combine two successive vectors
if the transactions look like a command-response pair.
4. Provide helper functions for common cases like supporting only 2
vectors at a time, supporting n vectors at a time, default vector
operation to cycle through all SPI op vectors one by one.
