add the WRN_DLY_SEL field for HW_GPMI_CTRL1.
This field is used as delay for gpmi write strobe.

The gpmi_nfc_compute_hardware_timing{} should contains all the
fields setting for gpmi timing registers. It already contains the fields
for HW_GPMI_TIMING0 and HW_GPMI_CTRL1.
So it is better to add a new field setting for HW_GPMI_TIMING1 in
this data structure. This makes the code more clear in logic.
This patch also changes some comments to make the code more readable.
