cpm_uart: Disable CPM udbg when re-initing CPM uart, even if not the console.
Previously, if udbg was using the CPM uart, and the normal CPM uart driver was enabled, but the console was directed elsewhere, udbg would not be stopped prior to initialization. This resulted in udbg hanging forever waiting for the CPM to process a descriptor. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
