Per MISRA C, operands to bit-wise operations should have unsigned
types. However, C99 prioritizes to use signed integers for hexadecimal constants
without the 'U' suffixes, leading to tons of bit operations on signed integers.
This patch series add the 'U' suffixes to the constants which are used in bit
operations, and add the intended width of these integers when applicable
(i.e. the target value is at least 32-bit wide) to avoid functional differences
due to signed vs. unsigned extensions. The rule of thumb is:
'0' for signed char/short/int
'0U' for unsigned char/short/int
'0L' for signed long (should be 64-bit)
'0UL' for unsigned long (should be 64-bit)
