There are some integer type conversions in the VMX, timer
and MTTR module detected by static analysis tool.
Update related integer type in VMX, timer and MTTR
module.
Add related constant value with 'U/UL' suffix.
V1-->V2:
Resolve few rebase conflicts.
V2-->V3:
Add 'h' for uint16_t argument in log function;
Update the type of temp variable 'type' as uint8_t
in MTTR module to reduce type conversion.
