Per datasheet, "HIGH AND LOW LIMIT REGISTERS", the lower 4 bit
of the limit registers are unused and always report 0.
The lower 4 bit should not be used for temperature comparisons,
so mask the unused bits before storing the limits.

Clear the ONE_SHOT bit in the WRITE path. Now than the READ path is

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

This commit adds a passthrough for PMBUS_IC_DEVICE_ID to allow Renesas
voltage regulators to return the integrated circuit device ID if they
would like to.
The behavior is very device specific, so it hasn't been added to the
general PMBUS model. Additionally, if the device ID hasn't been set,
then the voltage regulator will respond with the error byte value. The
guest error message will change slightly for IC_DEVICE_ID with this
commit.

Add an asynchronous version of i2c_send() that requires the slave to
explicitly acknowledge on the bus with i2c_ack().
The current master must use the new i2c_start_send_async() to indicate
that it wants to do an asynchronous transfer. This allows the i2c core
to check if the target slave supports this or not. This approach relies
on adding a new enum i2c_event member, which is why a bunch of other
devices needs changes in their event handling switches.

Currently there is no way for a board model's Kconfig stanza to
say "I have an i2c bus which the user can plug an i2c device into,
build all the free-standing i2c devices". The Kconfig mechanism
for this is the "device group". Add an I2C_DEVICES group along
the same lines as the existing PCI_DEVICES. Simple free-standing
i2c devices which a user might plausibly want to be able to
plug in on the QEMU commandline should have
default y if I2C_DEVICES
and board models which have an i2c bus that is user-accessible
should use
imply I2C_DEVICES
to cause those pluggable devices to be built.
In this commit we mark only a fairly conservative set of i2c devices
as belonging to the I2C_DEVICES group: the simple sensors and RTCs
(not including PMBus devices or devices which need GPIO lines to be
connected).
