media: i2c: adv748x: Add missing CBUS page
The ADV748x has 12 pages mapped onto I2C addresses.
In the existing implementation only 11 are mapped correctly in the page
enumerations, which causes an off-by-one fault on pages above the
infoframe definition due to a missing 'CBUS' page.
This causes the address for the CEC, SDP, TXA, and TXB to be incorrectly
programmed during the iterations in adv748x_initialise_clients().
Until now this has gone un-noticed due to the fact that following the
creation of the clients - the device is reset and the addresses are
reprogrammed in manually by the call to "adv748x_write_regs(state,
adv748x_set_slave_address);"
As part of moving to dynamic i2c address allocations repair this by
providing the missing CBUS page definition.
