A recent rearrangement of includes has lead to a problem on m68k

Resolve this by moving the block asm includes to below linux includes.
A side effect i that non-Sparc asm includes are now immediately
before Sparc asm includes, which seems nice.

Using sparse v0.6.4 I was able to reproduce this problem as follows
using the config provided by the kernel test robot:

$ wget https://download.01.org/0day-ci/archive/20230404/202304041748.0sQc4K4l-lkp@xxxxxxxxx/config
$ cp config .config
$ make ARCH=m68k oldconfig
$ make ARCH=m68k C=2 M=drivers/net/ethernet/sun
CC [M] drivers/net/ethernet/sun/sunhme.o
In file included from drivers/net/ethernet/sun/sunhme.c:19:
./arch/m68k/include/asm/irq.h:78:11: error: expected ‘;’ before ‘void’
78 | asmlinkage void do_IRQ(int irq, struct pt_regs *regs);
| ^~~~~
| ;
./arch/m68k/include/asm/irq.h:78:40: warning: ‘struct pt_regs’ declared inside parameter list will not be visible outside of this definition or declaration
78 | asmlinkage void do_IRQ(int irq, struct pt_regs *regs);
| ^~~~~~~

This seems like a problem with the header. m68k's asm/irq.h should include linux/interrupt.h before its declarations.

Compile tested only.
