Anastasia Klimchuk a69c5196d2 spi_master: Use new API to register shutdown function ...

This allows spi masters to register shutdown function in spi_master
struct, which means there is no need to call register_shutdown in init
function, since this call is now a part of register_spi_master.

As a consequence of using new API, two things are happening here:
1) No resource leakage anymore in case register_shutdown() would fail,
2) Fixed propagation of register_spi_master() return values.

Basic testing: when I comment out free(data) in linux_spi_shutdown, test
fails with error
../linux_spi.c:235: note: block 0x55a4db276510 allocated here
ERROR: linux_spi_init_and_shutdown_test_success leaked 1 block(s)
Means, shutdown function is invoked.

BUG=b:185191942
TEST= 1) builds and ninja test including CB:56911
2) On ARMv7 device
flashrom -p linux_spi -V
-> using linux_spi, chip found
3) On x86_64 AMD device
flashrom -p internal -V
-> this is actually using sb600spi, chip found
