To improve readability by saving horizontal and vertical space. Removed unecessary & 0xFF. Byte reading macros implemented in library/common.h, All files containing "& 0xff" were modified. Comments/Documentation not yet added to the macro definitions. Fixes #4274 Signed-off-by: Joe Subbiani <joe.subbiani@arm.com>
