After the commit 4007098f4ce4 (serial: sprd: Add power management for the Spreadtrum serial controller),
the 'enable' clock was forced to be configured in device tree, otherwise the uart devices couldn't be
probed successfully.

With this patch-set, the uart device which is used as console would be allowed to register even without
any clock configured in device tree, this will make debug easier.

Chunyan Zhang (3):
serial: sprd: check the right port and membase
serial: sprd: add console_initcall in sprd's uart driver
serial: sprd: keep console alive even if missing the 'enable' clock
