Add i.MXRT compatible string and cpu type support to lpuart driver,
to use little endian 32 bits configurations.
Also according to RM, the Receive RX FIFO Enable (RXFE) field in LPUART
FIFO register is bit 3, so this definition should change to 0x08 as done
for i.MX8. It needs also to set baudrate the same way as i.MX8 does.

Not all architectures(i.e. i.MXRT) support mxc_get_clock() and use DM_CLK
instead. So building could result in failure due to missing
mxc_get_clock().
Make if(CONFIG_IS_ENABLED(CLK)) an #if statement.

This commit adds board support for i.MXRT1050-EVK from NXP. This board
is an evaluation kit provided by NXP for i.MXRT105x processor family.
More information about this board can be found here:
https://www.nxp.com/design/development-boards/i.mx-evaluation-and-development-boards/i.mx-rt1050-evaluation-kit:MIMXRT1050-EVK
The initial supported/tested devices include:
- Debug serial
- SD

V1->V2:
* introduced CONFIG_IMXRT1050
* added imxrt1050-evk-u-boot.dtsi for imxrt1050-evk.dts

+How to use U-Boot on NXP i.MXRT1050 EVK
+-----------------------------------------------
+
+- Build U-Boot for i.MXRT1050 EVK:
+
+$ make mrproper
+$ make imxrt1050-evk_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot.img.
+
+- Flash the SPL image into the micro SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the micro SD card:
+
+sudo dd if=u-boot.img of=/dev/sdb bs=1k seek=128; sync
+
+- Jumper settings:
+
+SW7: 1 0 1 0
+
+where 0 means bottom position and 1 means top position (from the
+switch label numbers reference).
+
+- Connect the USB cable between the EVK and the PC for the console.
+(The USB console connector is the one close the ethernet connector)
+
+- Insert the micro SD card in the board, power it up and U-Boot messages should
+come up.

Hi Giulio,
> Add SDRAM driver for i.MXRT SoCs.
I would prefer more verbose description of this patch. For example
information if this code also performs auto calibration (it seems so)
and types of supported memories.
Is there any recommended tool from NXP, which helps with memory
calibration on a custom board? For example imx6q / Vybrid support auto
calibration in U-Boot (without the need of NXP closed source tooling).
