SoC: Intel: ACE: remove unused litelals parts in interrupt vectors

Currently the linker script for ACE defines memory regions for
literals in interrupt vector memory. This wastes memory and leads to
link failures when CONFIG_USERSPACE is enabled. Remove those regions
to reclaim 8 bytes per vector and fix linking. Also remove duplicated
level 4 interrupt vector sections and replace spaces with TABS.
