locking, m68k/asm-offsets: Rename pt_regs offset defines
In order to be able to use asm-offsets.h in C files the
existing namespace conflicts must be solved first. In
asm-offsets.h e.g. PT_D0 gets defined which is the offset of
the d0 member of the pt_regs structure. However a same define
(with a different meaning) exists in asm/ptregs.h.
So rename the defines created with the asm-offset mechanism to
PT_OFF_D0 etc. There also already exist a few defines with
these names that have the same meaning. So remove the existing
defines and use the asm-offset generated ones.
