Fix ATMEL_LCDC_MEMOR and ATMEL_LCDC_MEMOR_LITTLE defines to use "U"
cast to avoid shifting signed 32 bit values by 31 bit problem. This
problem. This is not a problem for gcc built kernel.
However, this may be a problem since the header is part of pbulic API
which could be included for builds using compilers which do not handle
this condition safely resulting in undefined behavior
