irqchip/irq-msi-lib: Optionally set default irq_eoi()/irq_ack()

msi_lib_init_dev_msi_info() sets the default irq_eoi()/irq_ack() callbacks
unconditionally. This is correct for all existing users, but prevents the
IMSIC driver to be moved to the MSI library implementation.

Introduce chip_flags in struct msi_parent_ops, which instruct the library
to selectively set the callbacks depending on the flags, and update all
current users to set them.
