`__main_thread_stack_base__` and `__main_thread_stack_end__` are
variables whose address is defined to be the corresponding part of the
stack. These are declared as `extern stkalign_t` in ChibiOS code, and
being declared as `extern uint32_t` in ArduPilot code creates a warning
at link time when using LTO. Correct the declaration to eliminate this
warning.
Also update `__main_stack_base__` and `__main_stack_end__` which don't
currently trigger this warning but serve similar purposes and so might
in the future.
The hardware expects an alignment of `stkalign_t` (which is 8 bytes) and
the linker script defines the variable values with this alignment as
well, so this is safe.
No code size or functional change.

this fixes an issue where when you lose R/C input on IOMCU that you
may not regain it when R/C comes back.
The issue stems from us still processing the DSM uart when we are
using the SD3 "SBUS" uart for RC input, and still doing the switch of
the SD3 config every 2 seconds.
When we are not searching for a new protocol we should not be changing
UART config
when we are looking for FPort input, we normally switch UART3 on the
IOMCU to 115200 to look for inverted inputs at 115200 baudrate. We
need to disable this switching when we have SBUS output enabled to
prevent a change in the SBUS output baudrate
