genirq: Make handle_enforce_irqctx() unconditionally available

Browse Source 
[ Upstream commit 8d187a77f04c14fb459a5301d69f733a5a1396bc ]

Commit 1b57d91b96 ("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.
