ppc: Freescale MPC52xx hardware definitions misc updates/fix

Mainly this includes :
 - Remove the 'volatile' keyword in structs defining hardware registers
   sets. This keyword is useless and can even be harmful if it makes someone
   believes it's sufficient to access a register like a variable. It's not !
   And the registers must be accessed with the appropriate in_be/out_be. So
   we remove this keyword as it's wrong and misleading.
 - Some fixes to SDMA
 - Add SDRAM & GPIO_WKUP unit
 - Remove of useless #define
