powerpc/44x: Fix build failure with GCC 12 (unrecognized opcode: `wrteei')
Building ppc40x_defconfig leads to following error
CC arch/powerpc/kernel/idle.o
{standard input}: Assembler messages:
{standard input}:67: Error: unrecognized opcode: `wrteei'
{standard input}:78: Error: unrecognized opcode: `wrteei'
Add -mcpu=440 by default and alternatively 464 and 476.
Once that's done, -mcpu=powerpc is only for book3s/32 now.
But then comes
CC arch/powerpc/kernel/io.o
{standard input}: Assembler messages:
{standard input}:198: Error: unrecognized opcode: `eieio'
{standard input}:230: Error: unrecognized opcode: `eieio'
{standard input}:245: Error: unrecognized opcode: `eieio'
{standard input}:254: Error: unrecognized opcode: `eieio'
{standard input}:273: Error: unrecognized opcode: `eieio'
{standard input}:396: Error: unrecognized opcode: `eieio'
{standard input}:404: Error: unrecognized opcode: `eieio'
{standard input}:423: Error: unrecognized opcode: `eieio'
{standard input}:512: Error: unrecognized opcode: `eieio'
{standard input}:520: Error: unrecognized opcode: `eieio'
{standard input}:539: Error: unrecognized opcode: `eieio'
{standard input}:628: Error: unrecognized opcode: `eieio'
{standard input}:636: Error: unrecognized opcode: `eieio'
{standard input}:655: Error: unrecognized opcode: `eieio'
Fix it by replacing eieio by mbar on booke.
