soc/intel/adl/chip.h: Convert all camel case variables to snake case

coreboot chip.h files mainly contains variable which allows board to
fill platform configuration through devicetree.
Since many of this configuration involves FSP UPDs, variable names were
in camel case which aligned with UPD naming convention.

By default coreboot follow snake case variable naming, so cleaning up
file to align all variable names as per coreboot convention.

During renaming process, this patch also removes unused variables
listed below:
-> SataEnable   // Checked in SoC code based on PCI dev enabled status
-> ITbtConnectTopologyTimeoutInMs // SoC always passes 0, so not used

Note: Since separating out changes into smaller CL might break the
compilation for the patch set, this is being pushed as a single big CL.

BUG=None
BRANCH=firmware-brya-14505.B
TEST=All boards using ADL SoC compiles with the CL.
