Subject: tty: serial: mpc52xx_uart: move static declarations up.

Avoid a compilation error so that they're not used before being
declared.

Fixes: 4d105880666a ("tty: serial: mpc52xx_uart: add bounds check for psc_num array index")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202609260356.tJWbd1WU-lkp@intel.com/
