serial: pxa: Staticize local symbols 

These local symbols are used only in this file.
Fix the following sparse warnings:

drivers/tty/serial/pxa.c:793:17: warning: symbol 'serial_pxa_pops' was not declared. Should it be static?
drivers/tty/serial/pxa.c:971:12: warning: symbol 'serial_pxa_init' was not declared. Should it be static?
drivers/tty/serial/pxa.c:986:13: warning: symbol 'serial_pxa_exit' was not declared. Should it be static?
