Jakub Kicinski 9297c32626 Revert "i2c: core: Dispose OF IRQ mapping at client removal time" 
[ Upstream commit a494457270 ]

This reverts commit e4df3a0b62
("i2c: core: Dispose OF IRQ mapping at client removal time")

Calling irq_dispose_mapping() will destroy the mapping and disassociate
the IRQ from the IRQ chip to which it belongs. Keeping it is OK, because
existent mappings are reused properly.

Also, this commit breaks drivers using devm* for IRQ management on
OF-based systems because devm* cleanup happens in device code, after
bus's remove() method returns.
