The uart_pipe_isr() double-checks whether rx interrupt occured by
calling uart_irq_is_pending() first. Get rid of that function call since
it is redundant (i.e. nothing more is done or checked inside that
conditional).

The VREFINT and TEMPSENSOR internal channels have a stabilization time
after they are enabled. Right now this just causes the first measure to
be a bit off, however with PR #47691 which stops the internal channels
after each readout, this is something important to respect. Fortunately
the stabilization time is available as constants in the HAL, so just
wait the time specified by the constants.
Note that the VBAT internal channel does not have any stabilization
time.

The LPUART driver activates the "noise" error interrupt but
neglects to clear the error bit when the interrupt occurs. This
causes the device to freeze. Clear the "noise" status to avoid
the lockup and track instances of this as a UART_ERROR_PARITY.

Inside gpio_nrfx_pin_interrupt_configure, the "ch" variable is allocated
inside the "if", but then it gets dereferenced and the pointer saved in
trigger_config, which is used in the outer context.
This works fine right now, but that memory location could possibly be
reused by another automatic variable if the code gets changed.
Moving it in the function context to avoid any potential problem.

using once single header to support multiple socs and product
generations is error prone and not easily maintained.
Over time we have been adding conditional code in headers and extending
structs to support new HW features which becomes a problem.
Goal is to keep platform headers in sync with hardware specification and
allow of introduction of new platforms and hardware features by just
introducing a new SoC with its own set of headers.
This is now just a copy of existing cavs-shim.h with slight changes,
goal is to clean this up long term and sync with hardware datasheets and
align on naming as well.
