spi_master: Move shutdown function above spi_master struct

Browse Source 
This patch prepares spi masters to use new API which allows to
register shutdown function in spi_master struct. See also later
patch in this chain, where spi masters are converted to new API.

BUG=b:185191942
TEST=builds and ninja test
Comparing flashrom binary before and after the patch,
make clean && make CONFIG_EVERYTHING=yes VERSION=none
binary is the same
