[RFC PATCH] Replaces long number representation by BIT() macro

[Leonardo Bras <leonardo@linux.ibm.com>]

The main reason of this change is to make these bitmasks more readable.

The macro ASM_CONST() just appends an UL to it's parameter, so it can be
easily replaced by BIT_MASK, that already uses a UL representation.

ASM_CONST() in this file may behave different if __ASSEMBLY__ is defined,
as it is used on .S files, just leaving the parameter as is.

However, I have noticed no difference in the generated binary after this
change.
