Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:
- Remove spi_xfer_two_vectors() which was fusing transactions to
accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
will trigger an error as these controllers can't support the api.

This replaces magic values by macros and adds some comments to improve
readability.
Adds a convenient function to fetch the test address of a rank.
Also fixes the temporary memory map by changing a write to MCHBAR
0x100 to 0x110, since this is what vendor does. (No difference
observed thus far)
TESTED on DG43GT

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.
TESTED on DG43GT (still works fine)

Stores information obtained from decoding dimms and receive enable
results for future use.
Depreciates using rtc nvram to store receive enable settings.
A notable change is that receive enable results are always reused, not
just on a resume from S3.
This requires cbmem to be initialized a bit earlier, right after the
raminit finished to be able to add the sysinfo struct to cbmem which
gets cached to the SPI flash in ramstage.
TESTED on Intel DG43GT with W25Q128.V. With 4 ddr2 dimms time in
raminit goes from 133,857ms (using i2c block read to fetch SPD) to
21,071ms for cached results.
