[PATCH v2 0/2] This is version 2 of the RZ/G2L support.

[Michele Bisogno <micbis.openwrt@gmail.com>]

This is version 2 of the RZ/G2L SoC support for the Renesas USBHS gadget driver.

Changes since v1:

    Split regulator changes into a separate patch.

    Refined FIFO PIO logic for better alignment handling.

Technical Justification:
While the Linux driver for RZ/G2L relies on DMA, this U-Boot implementation
focuses on the PIO path. The refactoring in fifo.c to use byte-level access
(ioread8/iowrite8) is necessary to handle trailing bytes and alignment
requirements specific to the RZ/G2L bus.

Additionally, explicit reset deassertion is added to the probe sequence,
and a re-entrancy fix (usb_del_gadget_udc) is included to prevent crashes
during repeated executions of gadget commands like 'ums'.
