Subject: [PATCH 00/11] irqchip: Pass platform device to platform drivers

The IRQCHIP_PLATFORM_DRIVER macros can be used to convert OF irqchip
drivers to platform drivers but currently reuse the OF init callback
prototype that only takes OF nodes as arguments. This forces drivers to
do reverse lookups of their struct devices during probe if they need
them for things like dev_printk() and device managed resources.

Half of the drivers doing reverse lookups also currently fail to release
the additional reference taken during the lookup, while other drivers
have had the reference leak plugged in various ways (e.g. using
non-intuitive cleanup constructs which still confuse static checkers).

Switch to using a probe callback that takes a platform device as its
first argument to simplify drivers and plug the remaining (mostly
benign) reference leaks.

Included are also some related preparatory fixes for an OF node
reference imbalance and section mismatches due to misplaced __init
markers (in some cases left over from platform driver conversions).
