[Mesa-stable] [PATCH] radeon/uvd: enable rate control for hevc encoding

[boyuan.zhang at amd.com]

From: Boyuan Zhang <boyuan.zhang at amd.com>

Set cu_qp_delta_enable_flag on when rate control is enabled, and set it
off when rate control is disabled (e.g. constant qp).

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110673
Cc: mesa-stable at lists.freedesktop.org

V2: fix typo and add bugzilla info
