[BUG] Incorrect pvParameters in RL78 FAR model tasks

[sauleThsQuin]

Describe the bug

In RL78 builds using the FAR data model, tasks created with xTaskCreate do not receive the correct pvParameters.
The function pxPortInitialiseStack() initializes the register image with dummy values (0x1111, 0xDEDE) instead of the actual pointer.
At the first context restore, the compiler’s prologue loads a corrupted parameter from A:DE.

Target

IDE : IAR Embedded Workbench for Renesas RL78 Version 5.10.3
IAR/RL78 port

To Reproduce

Build FreeRTOS for RL78 with FAR data model.
Create a task with xTaskCreate(task, "name", stack, pvParameters, prio, NULL).
Inspect pvParameters inside the task → the value is corrupted.

Expected behavior

Task entry functions should receive the correct pvParameters, passed in A:DE according to the RL78 FAR calling convention.

Thank you for raising issue and PR! Just like comments in PR, we'd start review after Renesas.
