drm/amd/display/dc/irq: Remove duplications of hpd_ack function from IRQ

2025-05-13T13:37:09Z

The major of dcn and dce irqs share a copy-pasted collection of copy-pasted function, which is: hpd_ack. This patch removes the multiple copy-pasted by moving them to the irq_service.c and make the irq_service's calls the functions implemented by the irq_service.c instead. The hpd_ack function is replaced by hpd0_ack and hpd1_ack, the required constants are also added. The changes were not tested on actual hardware. I am only able to verify that the changes keep the code compileable and do my best to look repeatedly if I am not actually changing any code.
