Add an ACPI device that is compatible with the Intel Virtual
Button kernel driver for reporting tablet mode state and various
virtual button events that may come from the EC.
This driver is used in Windows and in the Linux kernel at
drivers/platform/x86/intel-vbtn.c
Because of a check in the kernel driver it expects the board to
define the SMBIOS enclosure type as convertible for the check at
driver load time for tablet/laptop and dock/undock to work.
The virtual tablet mode button will proxy the tablet mode state
sent from the Sensor Hub to a SW_TABLET_MODE event in the kernel.
The virtual power button is used during S0ix for the EC to wake
the system with an SCI. There are separate press and release
events which are sent for completeness, although the kernel driver
will ignore the release event.
BUG=b:73137291

Have the generated Chrome OS ACPI GPIO table provide the ACPI GPIO
pin number instead of the raw GPIO number when possible.
This is necessary if the OS uses a different numbering for GPIOs
that are reported in ACPI than the actual underlying GPIO number.
For example, if the SOC OS driver declares more pins in an ACPI GPIO
bank than there are actual pins in the hardware it will have gaps in
the number space.
This is a reworked version of 6217e9beff
which does not try to convert CROS_GPIO_VIRTUAL.

Datasheets describe the used command as 'I2C Read' but adding the
word 'eeprom' in between should avoid further confusion with other
block commands.
Followups will add a symmetrical pair of commands i2c_block_read()
and i2c_block_write() that operate via I2C_EN bit and have a 32
byte size restriction on block transfers. For some hardware revision
these block commands are available, while 'I2C Read' was not.

Convert vboot_platform_prepare_reboot() to call a function in
soc//stoneyridge. A subsequent patch will add another call to
the new function, and this change removes any inference of a
dependency on vboot.
