Enabling APS6404L PSRAM on flexspi2 for TEENSY41 fails

[bdkrae]

Describe the bug
TEENSY41 board has an optional PSRAM chip (APS6404L). To enable it an overlay file was added to samples/drivers/memc. Building the sample for this target fails:

Mentioned type flexspi_device_config_t is defined in NXP mcux-sdk. It seems that the majority of nxp soc´s doesn´t have the struct member .addressShift, except the FRDM_RW612 and RD_RW612_BGA.

If line 225 is removed from memc_mcux_flexspi_aps6404l.c, then code builds properly and works like expected. Could this be a solution? Both boards FRDM_RW612 and RD_RW612_BGA are built correctly with the proposed solution, but the RD_RW612_BGA seems to have a deviating default value (addressShift=true) according to nxp-sdk. This should be checked on hardware for these boards.

To Reproduce
Steps to reproduce the behavior:

1. Insert overlay file teensy41.overlay with PSRAM config to samples/drivers/memc/boards:

/ {
	aliases {
		sram-ext = &aps6404l;
	};
};

&pinctrl {
	/* FLEXSPI2 for optional PSRAM/FLASH on TEENSY41*/
	pinmux_flexspi2: pinmux_flexspi2 {
		group0 {
			pinmux = <&iomuxc_gpio_emc_24_flexspi2_a_ss0_b>,
				<&iomuxc_gpio_emc_25_flexspi2_a_sclk>,
				<&iomuxc_gpio_emc_26_flexspi2_a_data0>,
				<&iomuxc_gpio_emc_27_flexspi2_a_data1>,
				<&iomuxc_gpio_emc_28_flexspi2_a_data2>,
				<&iomuxc_gpio_emc_29_flexspi2_a_data3>;
			drive-strength = "r0-6";
			slew-rate = "fast";
			nxp,speed = "100-mhz";
			input-enable;
		};
	};
};

&flexspi2 {
	status = "okay";
	pinctrl-0 = <&pinmux_flexspi2>;
	pinctrl-names = "default";
	reg = <0x402a4000 0x4000>, <0x70000000 DT_SIZE_M(8)>;
	/* APS6404L is 8MB, 64MBit pSRAM */
	aps6404l: aps6404l@0 {
		compatible = "nxp,imx-flexspi-aps6404l";
		size = <DT_SIZE_M(8 * 8)>;
		reg = <0>;
		spi-max-frequency = <DT_FREQ_M(109)>;
		status = "okay";
	};
};

2. west build -p -b teensy41 samples/drivers/memc
3. See error

Expected behavior
Should build and work properly.

Environment:

• OS: MacOS
• Toolchain: Zephyr SDK 0.16.8
• d789f33
