ARM: OMAP: Use __raw_read/write in irq.c

Also remove verbose debugging line for upstream merge.

Looks like with __raw_read/write the object code is sligtly
smaller (even with the debugging left out in the original code):

Old with omap_read/write:

00000000 <intc_bank_write_reg>:
   0:	e1a0c00d 	mov	ip, sp
   4:	e92dd800 	push	{fp, ip, lr, pc}
   8:	e24cb004 	sub	fp, ip, #4	; 0x4
   c:	e5913000 	ldr	r3, [r1]
  10:	e2833209 	add	r3, r3, #-1879048192	; 0x90000000
  14:	e7830002 	str	r0, [r3, r2]
  18:	e89da800 	ldm	sp, {fp, sp, pc}

0000001c <intc_bank_read_reg>:
  1c:	e1a0c00d 	mov	ip, sp
  20:	e92dd800 	push	{fp, ip, lr, pc}
  24:	e24cb004 	sub	fp, ip, #4	; 0x4
  28:	e5903000 	ldr	r3, [r0]
  2c:	e2833209 	add	r3, r3, #-1879048192	; 0x90000000
  30:	e7930001 	ldr	r0, [r3, r1]
  34:	e89da800 	ldm	sp, {fp, sp, pc}

New code with __raw_read/write:

00000000 <intc_bank_write_reg>:
   0:	e1a0c00d 	mov	ip, sp
   4:	e92dd800 	push	{fp, ip, lr, pc}
   8:	e24cb004 	sub	fp, ip, #4	; 0x4
   c:	e5913000 	ldr	r3, [r1]
  10:	e7820003 	str	r0, [r2, r3]
  14:	e89da800 	ldm	sp, {fp, sp, pc}

00000018 <intc_bank_read_reg>:
  18:	e1a0c00d 	mov	ip, sp
  1c:	e92dd800 	push	{fp, ip, lr, pc}
  20:	e24cb004 	sub	fp, ip, #4	; 0x4
  24:	e5903000 	ldr	r3, [r0]
  28:	e7910003 	ldr	r0, [r1, r3]
  2c:	e89da800 	ldm	sp, {fp, sp, pc}
