Subject: [PATCH 0/3] IRQ_DOMAIN: remove all "depends on", use only "select"

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set
it directly thru "make *config", so drivers should select it instead
of depending on it if they need it.
Relying on it being set for a dependency is risky.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

IRQ_DOMAIN is selected 109 times and is depended on 3 times in
current linux-next. Eliminate the uses of "depends on" by
converting them to "select".

 [PATCH 1/3] extcon: max8997: select IRQ_DOMAIN instead of depending on it
 [PATCH 2/3] of: OF_IRQ: select IRQ_DOMAIN instead of depending on it
 [PATCH 3/3] rtc: mt6397: select IRQ_DOMAIN instead of depending on it
