c32449a161 serial_lpuart: add support for i.MXRT
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.

126f884903 serial_lpuart: Update lpuart driver to support i.MX8
Add i.MX8 compatible string and cpu type support to lpuart driver,
to use little endian 32 bits configurations.

Also, according to RM, the Receive FIFO Enable (RXFE) field in LPUART
FIFO register is bit 3, so this definition should change to 0x08
(not 0x40) for i.MX8, otherwise the Receive FIFO is not disabled.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

7edf5c45f0 serial: lpuart: add i.MX7ULP support
Add i.MX7ULP support.
The buadrate calculation on i.MX7ULP is different,so add a new setbrg
function for i.MX7ULP.
Add a enum lpuart_devtype for runtime check for different platforms.
