arm64: pt_regs: swap 'unused' and 'pmr' fields

In subsequent patches we'll want to add an additional u64 to struct
pt_regs. To make space, this patch swaps the 'unused' and 'pmr' fields,
as the 'pmr' value only requires bits[7:0] and can safely fit into a
u32, which frees up a 64-bit unused field.

The 'lockdep_hardirqs' and 'exit_rcu' fields should eventually be moved
out of pt_regs and managed locally within entry-common.c, so I've left
those as-is for the moment.

There should be no functional change as a result of this patch.
