mb/google/octopus/variants/bobba: fix LTE power sequence and move

get_board_sku to smm stage.

fix Power_off section power sequence.
power_off_lte_module() should run in smm stage, add variant.c in smm stage.
also move get_board_sku() to mainboard_misc.c so that we can use it in smm stage
and ramstage.

BUG=b:144327240
BRANCH=octopus
TEST=build image and verify on the DUT with LTE DB.
