btw, as Bjron mentioned, there are a lot of these open coded BIT(n)..
but from a quick check, the first two or three I looked at, we already
have the appropriate defines in the rnndb generated headers, to
instead do:

/* Enable HDCP Encryption */
hdmi_write(hdmi, REG_HDMI_HDCP_CTRL,
HDMI_HDCP_CTRL_ENABLE |
HDMI_HDCP_CTRL_ENCRYPTION_ENABLE);

that seems somewhat more readable to me ;-)
