In drivers we use a family of printing functions including pr_err() and

via printf().
Our logging functions allow finer grained control of output. So replace
printf() by the matching logging functions. The usage of CONFIG_LOGLEVEL
remains unchanged.

This causes some fairly massive growth in various subsystems such as ubi
and we might want to look at what, if anything, we can do, before
growing some platforms by 15KiB (xilinx_zynqmp_virt) due to strings.
xilinx_zynqmp_virt has CONFIG_LOG enabled. Switching from printf() to
log() incurs size growth. Did you observe a size grows on platforms with
CONFIG_LOG=n?

Thanks.
