Arnd Bergmann pointed out that gcc-6 warns about passing negative signed

It appears that the register map constants are causing the warnings.
Actually, it might just be the (1 << 15) ones...
Convert all the constants as suggested by checkpatch.pl:
CHECK: Prefer using the BIT macro
The BIT() macro will make all the constants explicitly 'unsigned', which
helps to avoid the warning.
Fix the, unsused, DT2821_CHANCSR_PRESLA() macro. The "Present List
Address" (PRESLA) bits in the CHANCSR register are read only. This
define was meant to extract the bits from the read value.
