msm: vidc: Fix types of various members in shared structs

Several of the members shared with the firmware are supposed to be
32-bit integers.  To be consistent with definitions in the header files
shared with the firmware, convert all ints to u32s.

Also change struct hal_enable.enable from int to bool to prevent misuse
of the structure.
