The early serial should not be configured again in initcode() for BYPASS
boot mode and in start() for the other LDR boot modes.

In BYPASS boot mode, the start up code is located in Nor flash address other
than the DRAM address defined in link script. The code embedded string can't
be addressed by its compile time symbol. Calculate it according to the flash
offset.

Calculate the early uart clock from the system clock registers set by
the bootrom other than the predefine uboot clock macros.

Split the early baudrate setting function and the normal baudrate
setting one.
