Currently the code for VF setup/teardown done by a PF (if_create,
mac_add_config, link_status_query etc) is scattered; this patch
refactors this code into be_vf_setup() and be_vf_clear(). The
if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ
is created; so these cmds are now modified to use the MCCQ instead of
MBOX.

When a card is reset due to EEH error recovery or due to a suspend,
rx-mode config (promisc/mc) is not being sent to the FW. be_setup() is
called in these flows and is the best place for such config/re-config
cmds. Hence include rx-mode, vlan and flow-control config in
be_setup().

The algorithm described in the comment compares two reads from the RTC but
the code actually reads once and compares the result to an uninitialized

Since the device specific read_byte function is now always called, we need to be

Driver remove functions have an error return value, but rarely return an error
in practice. If a driver does return an error from its remove function, the
driver won't be unloaded and is expected to stay alive.
pmbus_do_remove() is defined as returning an int, but always returns 0 (no
error). Calling code passes that return value on to high level driver
remove functions, but does not evaluate it and removes driver data even if
pmbus_do_remove() returned an error (which it in practice never does). Even if
this code could never cause a real problem, it is nevertheless conceptually
wrong.
To reduce confusion and simplify the code, change pmbus_do_remove() to be a void
function, and have PMBus client drivers always return zero in their driver
remove functions.
