Solves the following Smatch warnings:
service_callback() warn: argument 7 to %lx specifier is cast from pointer
service_callback() warn: argument 11 to %lx specifier is cast from pointer
service_callback() warn: argument 12 to %lx specifier is cast from pointer
service_callback() warn: argument 13 to %lx specifier is cast from pointer
%p will print the hashed pointer to dynamic debug.
In order to print the unmodified pointer address, one can use the
`no_hash_pointers` via kernel parameters.

Drop vchiq_log_debug() macro which wraps dev_dbg(). Introduce the usage
of dev_dbg() directly.
Meanwhile at it, drop the usage of __func__ from the logs.
Dynamic debug supports this via the 'f' decorator flag.
Remove the entry from TODO regarding custom logging. VC04 is now
aligned according to the standard kernel logging mechanisms.

vchiq_add_connected_callback() logs using vchiq_log_error() macro,
but passes NULL instead of a struct device pointer. Fix it.
vchiq_add_connected_callback() is not used anywhere in the vc04_services
as of now. It will be used when we add new drivers(VC shared memory and
bcm2835-isp), hence it kept as it is for now.

The handle_to_service() helper can return NULL, so `service` pointer
can indeed be set to NULL. So, do not log through service pointer
(which can cause NULL-deference), instead, use the vchiq_instance
function argument to get access to the struct device.

mac_time and last_rx_desc_tsf are only used in
rtl92e_update_rx_pkt_timestamp(). Depending on a condition one is equal
to the other or vice versa. But since those are not used anywhere else
the function rtl92e_update_rx_pkt_timestamp() is just dead code.

Besides the IOCTL interface the VCHIQ character device also provides
a state dump of the whole VCHIQ driver via read. Moving the state dump
function to debugfs has a lot advantages:
- following changes on state dump doesn't break userspace ABI
- debug doesn't depend on VCHIQ_CDEV
- dump code simplifies a lot and reduce the chance of buffer overflows

The function vchiq_dump_service_state() is only used by vchiq_dump_state()
within vchiq_core.c. So move the definition of vchiq_dump_state() below
vchiq_dump_service_state() in order to make it static.
