usb: renesas_usbhs: Update usbhs pipe configuration for RZ/G2L family

The RZ/G2L family SoCs has 10 pipe buffers compared to 16 pipe buffers on
RZ/A2M. Update the pipe configuration for RZ/G2L family SoCs and use
family SoC specific compatible to handle this difference.

The pipe configuration of RZ/G2L is same as usbhsc_rzg2l_default_pipe[],
so select the default pipe configuration for RZ/G2L SoCs by setting
.has_new_pipe_configs to zero.

Add 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.
