Make immediate constants unsigned

Browse source 
PSA_KEY_LIFETIME_FROM_PERSISTENCE_AND_LOCATION shifts the location
value (location << 8). This can go outside the range of a 32-bit int
if the location value is above 2^23 as is the case here. Asan
rightfully complained about it. Make the value unsigned to avoid the
integer overflow.
