sandbox: fix registering multiple consoles ...

Consoles need to be registered with the "console" device name so that
they are probed by the correct driver. The barebox_register_console()
was already forcing this as it was overwriting the name that was being
passed as argument, but it was failing to provide a unique id for
each new console, so the underlying register_device() would just
return an error when wanting to re-register a device with device name
"console" and id 0.

We remove the unused name parameter from barebox_register_console() as
it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id,
so that a new unique device id is given to each newly registered
console device.

efi: add serial driver support ...

So now we can stop to use the efi-stdio as this driver
print on the Framebuffer and the serial at the same time.

This is specially usefull if we want to use the framebuffer via efi-gop for
something else.

Do not forget to disable the efi-stdio device before enabling the console
otherwise you will get double printing.

driver: replace dev_request_mem_region with dev_request_mem_resource ...

dev_request_mem_region doesn't work properly one some SoCs on which
PTR_ERR() values clash with valid return values from dev_request_mem_region.
Replace them with dev_request_mem_resource where possible.
