V4L/DVB: Remove the usage of I2C_HW_B_CX2388x on ir-kbd-i2c.c
Move the cx88 specific initialization for Hauppauge XVR remotes into cx88-input, removing the need for test it inside ir-kbd-i2c. The reference at cx88 for this symbol, at: drivers/media/video/cx88/cx88-i2c.c: core->i2c_adap.id = I2C_HW_B_CX2388x; drivers/media/video/cx88/cx88-vp3054-i2c.c: vp3054_i2c->adap.id = I2C_HW_B_CX2388x; Can't be removed yet, since lirc-i2c still uses it. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
