On RZ/G3S PFC register allow setting 8 functions for individual ports
(function1 to function8). For function1 register need to be configured
with 0, for function8 register need to be configured with 7.
We cannot use zero based addressing when requesting functions from
different code places as documentation (RZG3S_pinfunction_List_r1.0.xlsx)
states explicitly that function0 is GPIO.

For this add a new member to struct rzg2l_hwcfg that will keep the
offset that need to be substracted before applying a value to PFC register.

when I'm talking to journalists I just say "programmer" or something like that.
