Peter Maydell b5bf5a53d1 Kconfig: Add I2C_DEVICES device group
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).
