core: add of based component probing
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular device
can be detected by some firmware provided identifier, other times that
information is not available, and the kernel has to try to probe each
device.
Instead of a delicate dance between drivers and device tree quirks, this
change introduces a simple I2C component probe function. For a given
class of devices on the same I2C bus, it will go through all of them,
doing a simple I2C read transfer and see which one of them responds. It
will then enable the device that responds.

These are functions that are used by trace_printk() that allows to
quickly save the format and arguments into the ring buffer without
