[PATCH] PCI: acpiphp_ibm: add __ro_after_init to ibm_apci_table_attr

[Bhumika Goyal]

The object ibm_apci_table_attr of type bin_attribute structure is not
modified after getting initialized by ibm_acpiphp_init. Apart from
getting referenced in init it is also passed as an argument to the functions
sysfs_{remove/create}_bin_file but both the arguments are of type const 
struct bin_attribute *. Therefore add __ro_after_init to its declaration.
