bitfield: Add FIELD_MODIFY() helper
Add a helper for replacing the contents of bitfield in memory
with the specified value.
Even though a helper xxx_replace_bits() is available, it is not
well documented, and only reports errors at the run time, which
will not be helpful to catch possible overflow errors due to
incorrect parameter types used.
FIELD_MODIFY(REG_FIELD_C, ®, c) is the wrapper to the code below.
reg &= ~REG_FIELD_C;
reg |= FIELD_PREP(REG_FIELD_C, c);
Yury: trim commit message, align backslashes.
