Changes in V3:
1. Add the corresponding head files for GENMASK and FIELD_PREP to
avoid build break.
2. Remove the patch 2 and patch 3 in the original patch set, as the
loopback and RTS/CTS flags may not need to be cleared in .shutdown().

The patchset improve the Idle Line Interrupt for lpuart driver, also handle
the registers correctly for lpuart32 when closing the uart port.
Patches have been tested on imx8ulp-evk platform.
