When testing an i2c driver that is a fsi bus driver, I saw the following
oops:
kernel BUG at drivers/base/driver.c:153!

This is because the fsi bus had not been registered. This fix registers the bus
with postcore_initcall instead, to ensure it is registered earlier on.
When the fsi core is used as a module this should not be a problem as the fsi
driver will depend on the fsi bus type symbol, and will therefore load the core
before the driver.
Fixes:
