irqchip: Drop MSI_CHIP_FLAG_SET_ACK from unsuspecting MSI drivers

Commit 1c000dcaad2be ("irqchip/irq-msi-lib: Optionally set default
irq_eoi()/irq_ack()") added blanket MSI_CHIP_FLAG_SET_ACK flags,
irrespective of whether the underlying irqchip required it or not.

Drop it from a number of drivers that do not require it.
