Since All R-Car Gen3 SoCs have dedicated otg pins actually but
some boards don't use the otg pins (e.g. R-Car D3 Draak and R-Car E3
Ebisu), the driver should not choose SoC model base by using
rcar_gen3_phy_usb2_match_table's data. So, this patch checks a
"renesas,no-otg-pins" property to set the "uses_otg_pins".
Note that since r8a77995-draak.dts and r8a77990-ebisu.dts don't have
'dr_mode = "otg";' for now, if we apply this patch, no behavior
changes (the value of "uses_otg_pins" is false).

Most users of get/set array functions iterate consecutive bits of data,
usually a single integer, while processing array of results obtained
from, or building an array of values to be passed to those functions.
Save time wasted on those iterations by changing the functions' API to
accept bitmaps.
All current users are updated as well.
More benefits from the change are expected as soon as planned support
for accepting/passing those bitmaps directly from/to respective GPIO
chip callbacks if applicable is implemented.
