Fix parameter passing on m68k

Fix parameter passing on m68k

[Andreas Schwab]

On m68k function params are padded to 32 bits.  This fixes passing of
small structures.

	* m68k-tdep.c (m68k_gdbarch_init): Set parm_boundary instead of
	stack_align and deprecated_extra_stack_alignment_needed.
	(m68k_stack_align): Delete.
