Subject: [PATCH 1/8] genirq: Export more irq_chip_*_parent() functions

Git-commit: 65efd9a49af8174b2283fd5b27e9edf30e4483d0
Patch-mainline: v4.14-rc1
References: bsc#1105378

Many of the family of functions including irq_chip_mask_parent(),
irq_chip_unmask_parent() are exported, but not all.

Add EXPORT_SYMBOL_GPL to irq_chip_enable_parent,
irq_chip_disable_parent and irq_chip_set_affinity_parent, so they
likewise are usable from modules.
