disp: msm: sde: refactor sde_hw_interrupts to use offsets from catalog

Forráskód böngészése 
Refactor the SDE interrupts module to use the offsets in the catalog.
This avoids hard-coding offsets for interrupts within a block's
address space so when that block's base address is relocated the
interrupts for that block are shifted as well.
