These values are the difference between the offsets for the particular pins configuration registers, and offset 0x800 of the CONTROL_MODULE. Please check the AM335x TRM for more information.
The next value is what will be stored in this configuration register.
You wish to use the SPI0_SCLK and SPI0_D0 pins for UART2, which means that you have to multiplex them in mode1 (see the AM335x datasheet). Your pinmuxing should look like this:
uart2_pins: pinmux_uart2_pins {
pinctrl-single,pins = <
0x150 (PIN_INPUT_PULLUP | MUX_MODE1)/* spi0_sclk.uart2_rxd */
0x154 (PIN_OUTPUT_PULLDOWN | MUX_MODE1)/* spi0_d0.uart2_txd */
>;
