Update the pipe configuration for RZ/G2L family SoCs and use family SoC specific compatible to handle this difference. Added SoC specific compatible to OF table to avoid ABI breakage with old DTB. To optimize memory usage the SoC specific compatible will be removed later. The pipe configuration of RZ/G2L is same as the default one, so reuse the common table by renaming usbhs_default_pipe[]->usbhs_rcar_default_pipe[] and changing static qualifier to global to fill the pipe configuration data.
