feat(s32g274ardb): add DDR register accessories

Introduce a set of helper functions that
simplify register reads, bitfield updates,
AXI parity configuration and extraction
of training values.

These utilities encapsulate register access
patterns and are used for delay calibration,
Vref averaging, memory type detection and PLL
source selection.

feat(s32g274ardb): add DDR PHY mailbox support

Introduce mailbox handling between the DDR
controller and the PHY firmware, providing
mechanisms for message exchange, acknowledgments,
and execution status monitoring.

This enables reliable tracking of firmware
progress during DDR initialization and training,
