On failure, the platform_get_irq_byname prints an error message
so, patch removes error message related to this function from
core.c file.

A change was suggested during reviewing CDNSP driver by Chunfeng Yun.

Changelog:
v3
- changed error condition checking for dev_irq.
v2
- simplified code as sugested by Roger Quadros.
