On the DB410c we support running as a first stage bootloader. This
requires initialising the GPIOs which are muxed to UART before they can
be used. Add DM_FLAG_PRE_RELOC to the apq8016 pinctrl driver to ensure
that we do this early enough.
This is required to prevent the first few lines of UART log from being
dropped.
