Already released Linux versions did not have the needed ACPI-extension
in the RTC driver. If the ACPI-Support is enabled for the RTC, this
older Linux will not be able to use this device as it will be claimed by
the PNP-drivers. As there is no way to avoid that an older Linux kernel
meets a newer coreboot in the field, we need to disable the ACPI
support for the RTC for the mc_apl-based mainboards.

In commit b64db833d6 a basic ACPI support was added to the driver.
With this support an SSDT-entry is created for this RTC and it is now
visible to the OS via ACPI. In Linux the PNP-devices, which are
reported over ACPI, are scanned rather early and if the entry is found,
the device is claimed even if there is no driver available yet.
In this case, when the native RTC-driver without ACPI-support is loaded
and tries to register this device, the RTC is already blocked by the
PNP-drivers and cannot be used anymore. This leads to a non-usable RTC
on kernels where the needed ACPI-extension is not yet merged into the
RTC driver.
This patch provides a way to disable the ACPI-support for the RTC if
needed.

There use `z` as length modifier, as size_t should be always big enough

As `size_t` is defined as `long unsigned int` in i386-elf (32-bit), the
length modifier `l` matches there. With x86_64-elf/x86_64-linux-gnu
(64-bit) and `-m32` `size_t` is defined as `unsigned int` resulting in a

the length modifier `l` to make the code more readable.

Over the last couple of years we have continuously added more and more
CBMEM init hooks related to different independent components. One
disadvantage of the API is that it can not model any dependencies
between the different hooks, and their order is essentially undefined
(based on link order). For most hooks this is not a problem, and in fact
it's probably not a bad thing to discourage implicit dependencies
between unrelated components like this... but one resource the
components obviously all share is CBMEM, and since many CBMEM init hooks
are used to create new CBMEM areas, the arbitrary order means that the
order of these areas becomes unpredictable.
Generally code using CBMEM should not care where exactly an area is
allocated, but one exception is the persistent CBMEM console which
relies (on a best effort basis) on always getting allocated at the same
address on every boot. This is, technically, a hack, but it's a pretty
harmless hack that has served us reasonably well so far and would be
difficult to realize in a more robust way (without adding a lot of new
infrastructure). Most of the time, coreboot will allocate the same CBMEM
areas in the same order with the same sizes on every boot, and this all
kinda works out (and since it's only a debug console, we don't need to
be afraid of the odd one-in-a-million edge case breaking it).
But one reproducible difference we can have between boots is the vboot
boot mode (e.g. normal vs. recovery boot), and we had just kinda gotten
lucky in the past that we didn't have differences in CBMEM allocations
in different boot modes. With the recent addition of the RW_MCACHE
(which does not get allocated in recovery mode), this is no longer true,
and as a result CBMEM consoles can no longer persist between normal and
recovery modes.
The somewhat kludgy but simple solution is to just create a new class of
specifically "early" CBMEM init hooks that will always run before all
the others. While arbitrarily partitioning hooks into "early" and "not
early" without any precise definition of what these things mean may seem
a bit haphazard, I think it will be good enough in practice for the very
few cases where this matters and beats building anything much more
complicated (FWIW Linux has been doing something similar for years with
device suspend/resume ordering). Since the current use case only relates
to CBMEM allocation ordering and you can only really be "first" if you
allocate in romstage, the "early" hook is only available in romstage for
now (could be expanded later if we find a use case for it).

We would like to have an easy way to completely disable TPM support on a
board. For boards that don't pre-select a TPM protocol via the
MAINBOARD_HAS_TPMx options, this is already possible with the
USER_NO_TPM option. In order to make this available for all boards, this
patch just removes the whole USER_TPMx option group and directly makes
the TPM1 and TPM2 options visible to menuconfig. The MAINBOARD_HAS_TPMx
options can still be used to select defaults and to prevent selection of
a protocol that the TPM is known to not support, but the NO_TPM option
always remains available.
Also fix some mainboards that selected TPM2 directly, which they're not
supposed to do (that's what MAINBOARD_HAS_TPM2 is for), and add a
missing dependency to TPM_CR50 so it is set correctly for a NO_TPM
scenario.
