powerpc: Replace CONFIG_4xx with CONFIG_44x
Replace 4xx usage with 44x, and replace 4xx_SOC with 44x.
Also, as pointed out by Christophe, if 44x || BOOKE can be simplified to
just test BOOKE, because 44x always selects BOOKE.
Retain the CONFIG_4xx symbol, as there are drivers that use it to mean
4xx || 44x, those will need updating before CONFIG_4xx can be removed.
