When EMBEDDED is disabled, the EARLY_PRINTK option will be hiden and we
have no way to disable it.
For EARLY_PRINTK is not necessary for !EMBEDDED, we should make it
selectable and only enable it by default for EMBEDDED.

I hate to be a pedant, but how about if we don't make it depend on
EMBEDDED at all? I.E. just: 'default y'
If the system has SYS_HAS_EARLY_PRINTK, the overhead of enabling
EARLY_PRINTK is low, although it may slow down booting. But it is
really not at all related to EMBEDDED.

This option enables special console drivers which allow the kernel
to print messages very early in the bootup process.
