Log message:
* cdl/ser_powerpc_mpc555.cdl: Add HW queue option
* src/mpc555_serial_with_ints.c:
To help resolve an issue of characters being lost a software buffer
has been added between the Rx ISR and DSR when no hardware queue is
being used.
A cdl option to enable support the hardware queue on the first serial
port has been added. This enables 16 character hardware Tx and Rx
buffers to be used which allows continuous transmission and reception
of serial data and significantly improves performance.
