MA-12973 [AUTO] Skip serial init in board_init_f 

Serial init in board_init_f will cost much time, skip it here
because the serial will be initialized again in board_init_r
and it's more faster (after cache is enabled). We will miss
some logs before the serial is ready but it's ok for Android Auto.
This commit will save about 190ms on imx8qm.

Test: boot ok for both imx8qm and imx8qxp.
