regmap: Add hook for printk logging for debugging during early init Sometimes for failures during very early init the trace infrastructure isn't available early enough to be used. For this sort of problem defining LOG_DEVICE will add printks for basic register I/O on a specific device, allowing trace to be extracted when the trace system doesn't come up early enough to work with.
