could you please move these lines to vocore_vocore2.dts? these are board
specific properties.

have you tried adding these two lines?
	pinctrl-names = "default";
	pinctrl-0 = <&uart2_pwm_pins>;

pinctrl-1 should be removed. the driver never uses it.

board, you can add "select CONFIG_SPL_UART2_SPIS_PINMUX" here.
