This patch series solves multiple issues present in the driver. While
the patches are fairly independent, there are some dependencies. The
"sc16is7xx: Properly resume TX after stop" adds IER bit set function
that is later used in "sc16is7xx: Set AUTOCTS and AUTORTS bits".

Patches should be applied respecting the order in the series. This is
resend of the remaining patches in original series [1]. The resend is
needed because the "sc16is7xx: Fix for incorrect data being transmitted"
by Phil Elwell went in through tty-linus but the others did go to
tty-testing. Now that tty-linus is merged into Linux 5.17-rc6 and the
rc6 is merged into tty-testing, the patches apply cleanly.

Patch series has been developed and tested on a board with SC16IS760
connected via SPI bus.
