mpc8xx_pics_init() is now only a trampoline to
mpc8xx_pic_init().
Remove mpc8xx_pics_init() and use mpc8xx_pic_init()
directly.

In the same logic as commit be7ecbd240b2 ("soc: fsl: qe: convert QE
interrupt controller to platform_device"), convert CPM1 interrupt
controller to platform_device.

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h,
asm/pci.h etc...
Include the needed headers, and remove asm/prom.h when it was
needed exclusively for pulling necessary headers.

mpc8xx_pic_init() should return -ENOMEM instead of 0 when
irq_domain_add_linear() return NULL. This cause mpc8xx_pics_init to continue
executing even if mpc8xx_pic_host is NULL.

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.

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.
