According to reference manual, use of TC is "to avoid corrupting the
last transmission when the USART is disabled or enters Halt mode.". It
is safe to remove it since it is not checked when CONFIG_PM=n.

In the current implementation the STM32 UART driver required to enable
`CONFIG_PM_DEVICE` when `CONFIG_PM=y` to function properly. The main
reason is that in some situations, like in polling mode, transmissions
are not fully synchronous. That is, a byte is pushed to the _queue_ if
it is empty and then the function returns without waiting for it to be
transmitted to the wire. This makes sense to make things like per-byte
transmission efficient. However, this introduces a problem: the system
may reach idle state, and so enter low power modes before the UART has
actually finished the last data in the queue. If this happens,
communications can be interrupted or garbage data may be put into the
UART line.
The proposed solution in this patch uses PM constraints to solve this
problem. For the IRQ/DMA case it is easy since we can set the constraint
before transmission start, and when the completion (TC) interrupt is
received we can clear it. However, the polling mode did not have the
capability to signal the completion. For this case, a simpler IRQ
routine is provided to just release the constraint. As a result, the PM
hooks are not required and so system can operate with just `CONFIG_PM`.

This function wasn't being defined when SMP_BOOT_DELAY was set or when
SMP wasn't enabled. There's no reason for either, then function
doesn't depend on any kconfig-dependent build-time state, and (given
that we use -ffunction-sections) it won't appear in output binaries
unless called.
And there are use cases (e.g. z_smp_start_cpu()) where we need that
function even when BOOT_DELAY is enabled.
