Many drivers had started to use dev_err, dev_info, etc. for log functions. Currently, we are relying on <linux/compat.h>, but I guess the best home is <dm/device.h>, taking into account that Linux defines them in <linux/device.h>.

For now, I am leaving the ones in <linux/compat.h> because lots of Linux-originated code uses dev_*(), but the first argument is not struct udevice, so we need to ignore the bogus argument. More efforts are needed to iron out the issues.
