[PATCH v3 5/6] phy: renesas: phy-rcar-gen3-usb2: Control VBUS for RZ/G2L SoCs

[Biju Das]

Use regulator_set_hardware_enable_register() for controlling VBUS enable
for RZ/G2L alike SoCs in interrupt context.

Signed-off-by: Biju Das <biju.das.jz at bp.renesas.com>

v2->v3:
 * Replaced regulator's regmap API with newly introduced
   regulator_set_hardware_enable_register to enable/disable regulator
   in interrupt context.
 * Dropped using "usb_vbus-supply"
v1->v2:
 * Used regulator driver's regmap to handle VBUS.
