Replace assembler implementation of console_renesas_register() with
matching C implementation. Since it is now easily possible to pass
flags into console_renesas_register() and then onward to the console
initialization, adjust the signature of console_renesas_register()
and include the flags in it. Adjust both rcar_console_boot_init()
and rcar_console_runtime_init() to call console_renesas_register()
with its new combined set of parameters and drop console_set_scope()
invocation which is no longer needed, because the flags are passed
directly into console_renesas_register().
Drop console_renesas_flush() which is always a noop. Drop return
value from console_renesas_init() which is always 1.
