misc: rtsx: Enhance the signal handling processes in SVID/SSID 1028:0CE1 platform

Browse Source 
This patch introduces improvements to the signal handling processes on
the SVID/SSID 1028:0CE1 platform. By optimizing signal handling processes
we aim to deliver a more stable and reliable user experience.
The enhancements ensure robust connectivity and enhance signal process
performance. We have conducted extensive testing to ensure these
modifications result in noticeable improvements without impacting
existing functionalities.
