serial/mpc52xx_uart: prepare for adding MPC5125 PSC UART support

Browse source

MPC5125 PSC controller has different register layout than MPC5121.
To support MPC5125 PSC in this driver we have to provide further
psc_ops functions for SoC specific register accesses.

Add new register access functions to the psc_ops structure and
provide MPC52xx and MPC512x specific implementation for them.
Then replace remaining direct register accesses in the driver by
appropriate psc_ops function calls. The subsequent patch can now
add MPC5125 specific set of psc_ops functions.
