CB:38541 ("ec/google/chromeec: Add SSDT generator for ChromeOS EC")
added a new device_operations structure for chromeec for handling ACPI
SSDT generation. However, this resulted in the original
device_operations which handled lpc read resources to be skipped. This
change fixes the above regression by combining the device operations
for reading resources and ACPI SSDT generation into a single structure
and retains the old logic for enabling of pnp devices.

The following introduces helpers that, by default,
accommodate a larger SKU id space. The following
is the rational for that:
Allow INT32_MAX SKU id encodings beyond UINT8_MAX.
This allows for the SKU id to accommodate up to 4 bytes
however we reserve the highest bit for SKU_UNKNOWN to be encoded.
However, the legacy UINT8_MAX encoding is supported by leveraging
the Kconfig by overriding it with the legacy max of 0xff.
Follow ups migrate boards to this common framework.
V.2: Fixup array size && drop sku_id SKU_UNKNOWN check and pass
whatever is set to userspace as firmware doesn't care about
the value.
V.3: Use SPDX-License header.

Correct the offset for the Topstar driver enable/disable bit,
which was off by 2 bits compared to a dump of the AMI UEFI ACPI.
This prevents the fan mode (FANM) from being inadvertently changed

Upcoming patches for the Linux kernel (5.6 ?) would like to consume
information about the USB PD ports that are attached to the device. This
information is obtained from the CrOS EC and exposed in the SSDT ACPI
table.
Also, the device enable for this PCI device is moved from ec_lpc.c to
a new file, ec_chip.c, where EC-related ACPI methods can live. It
still allows other code to call functions on device enable (so that
PnP enable for the LPC device still gets called).

IMD provides support for small and large allocations. Region IMD Small memory is 1 KB
with 32 Bytes alignment, this region holds smaller entries without having to reserve a
whole 4 KB page. Remaining space is assigned to IMD Large to hold various regions with
4 KB alignment.
The UCSI kernel (kernel version 4.19) driver maps the UCSI_ACPI memory as not cached.
Cache mapping is set on page boundaries and all IMD Small is within the same page.
If another driver maps the memory as write-back before the UCSI driver is loaded then
the UCSI driver will fail to map the memory as not cached.
Placing UCSI_ACPI in IMD Large region will prevent this mapping issue since it will
now be located within its own page. This patch will force UCSI_ACPI region to be
located in IMD Large region.

The solution is to only enable the TEVT code in mainboard or SoC when an EC is used that uses

The TEVT method will be removed from the ASL code when the EC does not support TEVT.

Commit 77ad581ce [chromeec: PS2K node can't be under SIO node]
moved the PS2K ACPI device from under the SIO device to under
the LPCB, and while this fixed the keyboard under Windows for
Skylake devices, it was insufficient for Baytrail and Braswell
devices (and likely Apollo Lake/Gemini Lake too).
Moving the PS2K device under PCI0 allows the PS2K to be functional
under Windows for all Chrome-EC platforms.
Test: build/boot various Chrome-EC devices from IVB, HSW, BDW,
BYT, SKL, BSW, and KBL platforms, verify keyboard functional
under both Linux (4.x and 5.x) and Windows 10.

mainboard needs dock init (done with h8_mainboard_init_dock() in the
past) in ramstage, (discussed in CB:4294 where H8_DOCK_EARLY_INIT is
introduced) it can just do it in its own chip_ops.enable_dev function.
