powerpc: 52xx: Make immr_id DT match tables static
In some builds, the mpc52xx_pm_prepare()/lite5200_pm_prepare() functions
generate stack size warnings. The addition of 'struct resource' in commit
2500763dd3db ("powerpc: Use of_address_to_resource()") grew the stack size
and is blamed for the warnings. However, the real issue is there's no
reason the 'struct of_device_id immr_ids' DT match tables need to be on
the stack as they are constant. Declare them as static to move them off
the stack.
