As I read it, it doesn't have anything to do with any specific hardware,
it's just to catch bugs when people forget to initialize the structure
field:

arch/arm/mach-omap2/prcm44xx.h:
/*
 * OMAP4 PRCM partition IDs
 *
 * The numbers and order are arbitrary, but 0 is reserved for the
 * 'invalid' partition in case someone forgets to add a
 * .prcm_partition field.
 */
#define OMAP4430_INVALID_PRCM_PARTITION         0
