Update Data Structures to Preserve 32-Bit Data in Register Layouts

In the 64-bit data model, data structures that use long to define the type of arguments might be incorrect if the argument needs to define a 32-bit quantity. For example, some drivers currently use long to define 32-bit fields in a hardware register layout. To make a driver 64-bit safe, update data structures where necessary to use int32_t or uint32_t, defined in <sys/inttypes.h>, instead of long for 32-bit data. This preserves the binary layout of 32-bit data structures.

For example, change:

struct reg {
 	ulong_t			addr;
 	uint_t			count;
}

to:

struct reg {
 	uint32_t			addr;
 	uint32_t			count;
}
