HV:treewide:Update the type of return value and parameters of atomic operations

Browse Source 
There are many type conversions in the atomic
operations invoking reported by static analysis tool. These
type conversions voilate MISRA C.

To keep uniform naming convention, rename atomic operation
function names:
atomic_set_int/long --> atomic_set32/64;
atomic_clear_int/long --> atomic_clear32/64;
atomic_load --> atomic_load32;
atomic_store --> atomic_store32;
atomic_swap --> atomic_swap32;
atomic_readandclear --> atomic_readandclear32;
atomic_inc --> atomic_inc32;
atomic_dec --> atomic_dec32;
atomic_cmpxchg --> atomic_cmpxchg32;
atomic_xadd --> atomic_xadd32.
Update the type of atomic_load32/64, atomic_store32/64,
atomic_swap32/64, atomic_cmpxchg32/6.
Update related variables and callers.

Note: the type of return value and parameters of atomic_xadd32/64
still keep signed int/long since caller pass
negative variable to atomic_xadd32/64;

V1-->V2:
	Add comments for atomic_set/clear to differ from
	bitmap_set/clear.
