For modules having single clock, clk_get should be done with dev_id.
But current davinci implementation handles multiple instances
of the UART devices with single platform_device_register. Hence clk_get
is based on con_id rather than dev_id, this is not correct. Do
platform_device_register for each instance and clk_get on dev_id.

Since v2:
1) Added missing sentinel value for struct plat_serial8250_port, .flags = 0.
2) Added sentinel value for struct platform_device serial_device array's.
