Config option SOC_INTEL_COMMON_BLOCK_HDA is currently used for
initialization of HDA codecs only. This prevents adding of any static
devices under the HDA device node. However, there can be boards which
want to add devices under HDA node (e.g. nocturne that wants to
provide DMIC properties to OS) without performing any codec
initialization using the HDA. This change:
1. Adds a new config option SOC_INTEL_COMMON_BLOCK_HDA_VERB that can
be set explicitly by the boards that want to perform codec
initialization.
2. Uses newly added config option is used to guard the initialization
functions for the codec. Rest of the device operations can still be
used by all the other boards without having to use HDA codec
initialization.
3. Selects the newly added option SOC_INTEL_COMMON_BLOCK_HDA_VERB in
kblrvp which is the only board enabling HDA codec initialization
using common block code.
4. Selects original config SOC_INTEL_COMMON_BLOCK_HDA for skylake SoC.
Above changes need to be bundled and pushed in as a single change in
order to avoid breaking existing users.

Move funtions callbacks used to override FSP upd values to
separate files. This serves as a base change for SoCs for which
FSP is still under development, and hence the FSP header files
are not available yet and in turn the UPDs cannot be referred.
These newer SoCs will implement empty callbacks. The code will
compile with basic header files which only include the architectural
FSP structures.
This allows plugging in these separate files for compilation in an
environment where FSP header files are available.
The fact is, FSP header files are not released externally until PRQ.
However the teams at intel and some partners have access to the development
version of these files. This code refactor helps to continue development
on the pre-PRQ silicons and submit related code to coreboot.org.

Use GPIO GPP_D17 pin as the EC sync interrupt and provide this value
to the embedded controller to be exported to the OS.
This interface was tested on a reworked Nocturne board with modified
EC and a modified kernel driver to ensure that the interrupt asserts
as expected and can be used by the kernel driver.

Some boards are adding a second pin used for synchronization between
the EC and AP. This is a direct connection between the EC and the SOC
that is intended to provide a lower latency interrupt signal for
sensors on the EC.
Currently the runtime EC interrupts assert an SCI before eventually
resulting in a Notify() on the MKBP device that the sensor driver users.
These extra layers add processing time and require additional EC
communication to determine the event source.
