staging: greybus: remove timesync protocol support

While the timesync protocol was a great idea, it never ended up getting
implemented by any known hardware devices.  It's also a bit
"interesting" in how it ties into the platform controller.

So, just remove it for now.  It's not needed, no one uses it, and it's a
stumbling block in getting the greybus core code merged out of the
staging tree.  If anyone wants it in the future, reverting this patch is
a great place to start from.

staging: gdm724x: update HCI structs with new bitwise types

Update the driver's HCI structs and associated endian-converter
functions with new driver-specific bitwise types. The new types
encourage correct endian-handling within the driver by triggering
sparse warnings when mixing with other types. The driver's
endian-converters provide correct and warning-free conversions.

Driver-specific bitwise types are used instead of the standard
endian-specific types because the attached device can be of either
endian. This is also why the driver has its own endian-conversion
functions, which consider endianness of both the cpu and the attached
device.

Introducing the new types to the converters fixes the sparse warnings:

staging: greybus: add host device function pointer checks

Add sanity checks for cport_quiesce and cport_clear before invoking the
callbacks as these function pointers are not required during the host
device registration. This follows the logic implemented elsewhere for
various other function pointers.

staging: greybus: loopback: use gb_loopback_async_wait_all don't spin

Currently the greybus-loopback thread logic spins around waiting for
send_count == iteration_max which on real hardware doesn't make a
difference to us but in simulation is excruciatingly slow, anti-social and

continuing when the send_count == iteration_max and go to sleep until
there's something worthwhile to-do.
