Everything is wrong here, the Kconfig symbols are only the tip of the
iceberg. Based on Kconfig prompts the SoC code performed pad configu-
rations! I don't see why the person who configures coreboot should have
the board schematics at hand.
As a mitigation, we remove the prompts for UART_DEBUG, which is renamed
to INTEL_LPSS_UART_FOR_CONSOLE (because the former didn't really say
what it's about), and for UART_FOR_CONSOLE in case the former is selec-
ted.

In some situations the GPIO pad numbers used by the OS are not
contiguous and coreboot must provide a way for ACPI to provide
the expected GPIO number to the OS.
To do this each GPIO group can now have a pad base value, which
will be used as the starting pin number for this group and it
is added to the relative pin number of this GPIO to compute the
ACPI pin number for a particular GPIO.
By default this change has no effect because the existing uses
of INTEL_GPP() will set the pad base to PAD_BASE_NONE and the
GPIO number is used as the ACPI pin number without translation.

To not bloat src/Kconfig up any further, start a new `Kconfig.debug`

If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.

Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also
implement board_reset() as a "full reset" (aka. cold reset) as that
is what was used here for hard_reset().
Drop soc_reset_prepare() thereby, as it was only used for APL. Also,
move the global-reset logic.
We leave some comments to remind us that a system_reset() should
be enough, where a full_reset() is called now (to retain current
behaviour) and looks suspicious.
Note, as no global_reset() is implemented for Denverton-NS, we halt
there now instead of issuing a non-global reset. This seems safer;
a non-global reset might result in a reset loop.
