imx8mq_evk: Staticize when appropriate

Staticize 'spl_dram_init' and 'i2c_pad_info1' to fix the
following sparse warnings:

board/freescale/imx8mq_evk/spl.c:30:6: warning: symbol 'spl_dram_init' was not declared. Should it be static?
board/freescale/imx8mq_evk/spl.c:41:22: warning: symbol 'i2c_pad_info1' was not declared. Should it be static?
