arm64: ptrace: Replace interrupts_enabled() with regs_irqs_disabled()
The generic entry code expects architecture code to provide
regs_irqs_disabled(regs) function, but arm64 does not have this and
provides interrupts_enabled(regs), which has the opposite polarity.
In preparation for moving arm64 over to the generic entry code,
relace arm64's interrupts_enabled() with regs_irqs_disabled() and
update its callers under arch/arm64.
For the moment, a definition of interrupts_enabled() is provided for
the GICv3 driver. Once arch/arm implement regs_irqs_disabled(), this
can be removed.
Delete the fast_interrupts_enabled() macro as it is unused and we
don't want any new users to show up.
No functional changes.
