mtd: rawnand: qcom: Add helper to configure location register
Create a nandc_set_read_loc() helper to abstract the
configuration of the location register.
QPIC v2 onwards features a separate location register
for the last codeword, so introducing this extra helper
which will simplify the addition of QPIC v2 support.
