Kernel: Disable interrupt signaling for the SD driver

Browse source 
Currently we do not use interrupts for the SD driver, yet we
had enabled the signaling of all of them.
Since we were never acknowledging them, we were getting spammed by
unnecessary interrupts, causing the system to slow down to a crawl.

This commit makes the system boot in less than 1 minute with PIO,
compared to the old 30+ minute boot.
