This patch pushes these large default delay tables to a different file
to reduce cluttering up the actual raminit source. While doing so it
also uses more but smaller arrays and also adds the respective default
delays for DDR3 which are not yet used in this patch.
This patch add a function to set the read DQS delays instead of just
programming magic values. (This will prove useful for DQS read
training)
To prepare for adding trainings on the delay values it stores these
default delays in the sysinfo struct to program those. Later when
trainings are implemented those trained values will be used instead of
these safe default values, via using the cached sysinfo in 'mrc'
cache.

This requires cbmem to be initialized a bit earlier, right after the

gets cached to the SPI flash in ramstage.

The pch_smbus_init() function contains code to enable clock gating for
the SMBus controller. Unfortunately this code is buggy and leads to a
hanging system with the latest microcode version.
The hang occurs as follows:
The clock gate register is mapped into RCBA space. After reading the
RCBA address from the LPC device config space no mask is applied to the
value (only bits 31..14 are valid while bit 0 is the enable bit). For
this reason the final address is off by one. The old microcodes at least
allowed this unaligned access to the RCBA space. With the latest
microcode this access leads to CPU hang.
Once this is fixed the next issue occurs: After setting the clock
gating bit for SMBus (bit 5) the SMBus controller disappears from the
PCI bus completely and hence no usage of it is possible anymore.
To fix this issue the clock gating code is completely removed as it was
intentionally meant to enable clock gating on the SMB_CLK line and not
the clock gating on the PCIe interface of the SMBus controller.
This issue is known already and was discussed on the mailinglist:

Required for other ACPI generators, like the one used for _ROM.
* Add ACPI code for PEG10/PEG11/PEG12/PEG60 and include it on all platforms.
* Add PCIe driver for PEG. The driver returns ACPI names for ssdt generators.
Needs test on real hardware.
