[PATCH 1/4] dt-bindings: phy: qcom,snps-eusb2-phy: Make resets optional

[Shawn Guo]

From: Bartosz Golaszewski <bartosz.golaszewski at oss.qualcomm.com>

Not every instance of this PHY has a block reset of its own. On Nord
SoC there are three eUSB2 PHYs but only two QUSB2PHY block resets:
the HS-only USB20 tile has no dedicated PHY reset and is instead reset as
a whole through the controller's own USB20_PRIM_BCR. Requiring 'resets'
makes that instance impossible to describe, since the controller and the
PHY cannot both claim the single block reset exclusively.

The driver has always treated the reset as optional - it uses
devm_reset_control_get_optional_exclusive() - and the sibling
samsung,exynos2200-eusb2-phy binding, which is served by the same driver,
does not require it either. Drop it from the required list.
