hw/arm/omap1: Convert raw printfs to qemu_log_mask()

omap1.c is very old code, and it contains numerous calls direct to
printf() for various error and information cases.

In this commit, convert the printf() calls that are for either guest
error or unimplemented functionality to qemu_log_mask() calls.

This leaves the printf() calls that are informative or which are
ifdeffed-out debug statements untouched.
