[patch 1/2] genirq: Make handle_enforce_irqctx() unconditionally available

[Thomas Gleixner]

Commit 1b57d91b969c ("irqchip/gic-v2, v3: Prevent SW resends entirely")
sett the flag which enforces interrupt handling in interrupt context and
prevents software base resends for ARM GIC v2/v3.

But it missed that the helper function which checks the flag was hidden
behind CONFIG_GENERIC_PENDING_IRQ, which is not set by ARM[64].

Make the helper unconditionally available so that the enforcement actually
works.
