ARM: 6465/1: Fix data abort accessing proc_info from __lookup_processor_type
Commit 5085f3ff458521045f7e43da62b8c30ea7df2e82 added better support for CONFIG_HOTPLUG_CPU by keeping proc_info around. However, depending on the Kconfig options selected, this can make the booting fail mysteriously early on. Turns out a data abort can happen in __lookup_processor in ldmia r5 {r3, r4}. When it happens the address loaded to r5 is not aligned. Fix the problem by aligning proc_info.
