When DDR is in synchronous mode, the existing code assigns sysclk
frequency to DDR frequency. It should be synchronous with the platform
frequency. CPU frequency is based on platform frequency in synchronous

* Fixes the bit mask for DDR_SYNC (RCWSR5[184])
* Corrects the detection of synchronous mode.

Extend mpc512x serial driver to support multiple PSC ports.
Subsequent patches for PDM360NG board support make use of this
functionality by defining CONFIG_SERIAL_MULTI in the board config
file. Additionally the used PSC devices are specified by defining
e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6.
Support for PSC devices other than 1, 3, 4 and 6 is not added
by this patch because these aren't used currently. In the future
it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and
INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c.
Additionally you have to add code for registering added
devices in serial_initialize() in common/serial.c.
serial: struct serial_device: add uninit() entry for drivers
Subsequent patch extends mpc512x serial driver to support
multiple PSC ports. The driver will provide an uninit()
function to stop the serial controller and to disable the
controller's clock. Adding uninit() entry to struct serial_device
allows disabling the serial controller after usage of
a stdio serial device.
This patch adds uninit() entry to the struct serial_device
and fixes initialization of this structure in the code
accordingly.
