Anthony PERARD f41eb7ba3e xen/arm: Configure early printk via Kconfig ...

At the moment, early printk can only be configured on the make command
line. It is not very handy because a user has to remove the option
everytime it is using another command other than compiling the
hypervisor.

Furthermore, early printk is one of the few odds one that are not
using Kconfig.

So this is about time to move it to Kconfig.

The new kconfigs options allow a user to eather select a UART driver
to use at boot time, and set the parameters, or it is still possible
to select a platform which will set the parameters.

If CONFIG_EARLY_PRINTK is present in the environment or on the make
command line, make will return an error.
