rS346633: Implement pic_pre_ithread(), pic_post_ithread().
Summary

These are required to properly handle interrupts in the interrupt thread.

Instead of disable/enable interrupts in pre_ithread()/post_ithread() respectively, play with priority register (priority 0 effectively disables interrupt on all the cores).

Test Plan

Tested with Cadence network adapter on HiFive Unleashed
