Shenwei Wang 6909ec0bd6 irqchip/imx-irqsteer: Handle runtime power management correctly 
[ Upstream commit 33b1c47d1fc0b5f06a393bb915db85baacba18ea ]

The power domain is automatically activated from clk_prepare(). However, on
certain platforms like i.MX8QM and i.MX8QXP, the power-on handling invokes
sleeping functions, which triggers the 'scheduling while atomic' bug in the
context switch path during device probing:

 BUG: scheduling while atomic: kworker/u13:1/48/0x00000002

Cure this by implementing the irq_bus_lock/sync_unlock() interrupt chip
callbacks and handle power management in them as they are invoked from
non-atomic context.
