sparc: Make '-p' boot option meaningful again.
If "-p" is given on the command line, clear the CON_BOOT flag for the initial early boot PROM console. This is necessary to try and see crash messages that occur between the registry of the VT console and the probing of the first framebuffer or serial console. During this time no console messages are emitted because the VT console registry (even if no backend is registered to it) removes the early console if CON_BOOT is set. Signed-off-by: David S. Miller <davem@davemloft.net>
