am33xx: refactor emif4/ddr to support multiple EMIF instances

Browse Source 
The AM33xx emif4/ddr support closely matches what is need to support
TI814x except that TI814x has two EMIF instances. Refactor all the
emif4 helper calls and the config_ddr() init function to use an
additional instance number argument.
