There was a bug I2C adapter writes and reads one byte too much.
As the most I2C clients has auto-increment register addressing
this leads next register from the target register overwritten by
garbage data.
As a change remove whole register address byte usage and write
data directly to the I2C bus without saying what are register
address bytes to firmware.

The i2c failures were caused by enabling both i2c gates
at the same time while putting the tuners asleep.
This patch removes the init() and sleep() callbacks from the tuner,
to prevent frontend.c from calling
i2c_gate_ctrl
tuner init / sleep
i2c_gate_ctrl
without holding the lock.
tuner init() and sleep() are instead called in frontend init() and
sleep().

struct dvb_usb_device *d can never be NULL so don't waste time
checking for this.
Rationale: the urb's context is set when usb_fill_bulk_urb() is called
in dib0700_rc_setup(), and never changes after that. d is dereferenced
unconditionally in dib0700_rc_setup() so it can't be NULL or the
driver would crash right away.
