mtd: nand: denali: use more FIELD_PREP / FIELD_GET where appropriate
In several places in this driver, the register fields are retrieved
as follows:
val = reg & FOO_MASK;
Then, modified as follows:
reg &= ~FOO_MASK;
reg |= val;
This code relies on its shift is 0, which we will never know until
we check the definition of FOO_MASK. Use FIELD_PREP / FIELD_GET
where appropriate.
