V4L/DVB (10800): Add support for ST LNBH24 LNB power controller.
The controller consist of two independent parts. Every part is similar to LNBP21, but has configurable i2c address. It is used in NetUP Dual DVB-S2 CI card. http://linuxtv.org/wiki/index.php/NetUP_Dual_DVB_S2_CI Signed-off-by: Igor M.
