e62836b7d6 soc/intel/common/block: Move i2c common functions into block/i2c
This patch cleans soc/intel/{apollolake/cannonlake/skylake} by moving
common soc code into common/block/i2c.

BUG=b:78109109
BRANCH=none
TEST=Build and boot KBL/CNL/APL platform.

c4986eb7f4 soc/intel/common/block: Add common chip config block
Adding common chip config structure which will be used to return data to
common code. When common code requires soc data, code used to fetch
entire soc config structure. With this change, common code will only get
the data/structure which is required by common code and not entire
config.

For now, adding i2c, gspi and lockdown configuration which will be used
by common code.

BUG=none
BRANCH=b:78109109
TEST=compile code for APL/SKL/CNL. Boot using SKL/APL/CNL and check
values are returned properly using common structure.

b94a27506e drivers/i2c/designware: reduce API complication for bus config
Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement
that callback for obtaining the bus config. However, we're currently
forcing another parameter of struct device so one can do the lookup.
This works for Intel-based systems since the struct device was needed
to program the BAR, etc. However, from an API standpoint, it just
complicates matters by needing to obtain the struct device. The SoC
already has knowlege of its own devices so it can get the config
itself by bus number. Therefore, remove that contraint from the API.

9aee8194c4 drivers/i2c/designware: namespace soc functions
Rename the following functions to ensure it's clear that the designware
i2c host controller driver is the one that these functions are
associated with:

i2c_get_soc_cfg() -> dw_i2c_get_soc_cfg()
i2c_get_soc_early_base() -> dw_i2c_get_soc_early_base()
i2c_soc_devfn_to_bus() -> dw_i2c_soc_devfn_to_bus()
i2c_soc_bus_to_devfn() -> dw_i2c_soc_bus_to_devfn()
