arm64: entry.S: convert el1_sync
el1_sync unmasks exceptions on a case-by-case basis, debug exceptions are unmasked, unless this was a debug exception. IRQs are unmasked for instruction and data aborts only if the interupted context had irqs unmasked. Following our 'dai' order, el1_dbg should run with everything masked. For the other cases we can inherit whatever we interrupted. Add a macro inherit_daif to set daif based on the interrupted pstate.
