V4L/DVB: tm6000: Add request at Req07/Req08 register definitions

Use a pair Req/Reg for all registers at req07 and req08 groups. This
makes easier to replace them at the code with a script and helps to
avoid using the wrong req with some register.

This change were generated by this script:

if (m/^(\#define TM6010_REQ)([0-9].)([^\s]+)(\s+)0x([A-F0-9].)/) {
$name="$1$2$3"; $sp=$4; $req=$2; $val=$5; $val=~tr/A-F/a-f/; printf
"$name%s0x%s, 0x%s\n", $sp, $req, $val; } else { print $_ }
