[Marek Vasut <marek.vasut+renesas@mailbox.org>]

From: Nguyen Tran <nguyen.tran.pz@bp.renesas.com>

Add support for the Renesas R-Car M3Le (R8A779MD) SoC, a variant of the
R-Car M3-N (R8A77965) SoC. The Renesas M3Le SoC is a register-compatible
variant of the R8A77965 (M3-N) with reduced set of peripherals.

V2: - Drop DU until it can be tested
    - Reinstate sdhi3, switch SDHI to dedicated M3Le compatible strings
    - Add no-mmc DT property to SDHI3/MMC1, because MMC1 is not supported
    - Disable ohci1, ehci1, usb2_phy1
