[PATCH v2 1/7] powerpc/eeh: Use debugfs_create_u32 for eeh_max_freezes

[Oliver O'Halloran <oohall@gmail.com>]

There's no need to the custom getter/setter functions so we should remove
them in favour of using the generic one. While we're here, change the type
of eeh_max_freeze to u32 and print the value in decimal rather than
hex because printing it in hex makes no sense.

v2: Replaced uint32_t with u32.
