arm: dts: ls1028a: sync the fsl-ls1028a.dtsi with linux
Now that everything is prepared, copy the fsl-ls1028a.dtsi from the
linux kernel v5.14.12.
Notable changes:
- second watchdog added
- the number of chip selects of the SPI controller is now correct and
reflects what the hardware offers
- the LPUARTs have the correct clock parent
- USB controllers are enabled by default, which was already the case
before this sync because all board enabled all the USB controller
nodes. A linux patch to fix this is pending.
- the eSDHC controller changes from big-endian to little-endian, but
that property seems to be not used at all.
