Subject: [PATCH] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Drop `bias-pull-up` from OVC pins

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

The USB20/21_OVRCUR pins on the RZ/V2H EVK has an external pull-up resistor
on the board. Therefore, the internal pull-up configuration via the
`bias-pull-up` property is redundant and should be removed.

Fixes: 7548897ad4ae3 ("arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Enable USB2.0 support")
