Christophe Leroy 132f92fdc4 powerpc/8xx: add __init to cpm1 init functions 
Functions cpm1_clk_setup(), cpm1_set_pin(), cpm_pic_init() and
mpc8xx_pic_init() are only called from __init functions, so mark
them __init as well.

Wen Yang cc76404fea powerpc/8xx: Fix possible device node reference leak 
The call to of_find_compatible_node() returns a node pointer with
refcount incremented thus it must be explicitly decremented after the
last usage.

irq_domain_add_linear() also calls of_node_get() to increase refcount,
so irq_domain() will not be affected when it is released.

Detected by coccinelle.

Fixes: a8db8cf0d8 ("irq_domain: Replace irq_alloc_host() with revmap-specific initializers")
