[media] DocBook: better document FE_DISEQC_SEND_BURST ioctl
Use the proper format for FE_DISEQC_SEND_BURST documentation and improve the documentation. Keep the enum fe_sec_mini_cmd description together with the ioctl, as both are used together. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
