Hi,

These are only the ahb bus gates, not the module clocks.
Naming them lcd might be a bit confusing, but it follows the naming we
used since sun4i. And the tcon modules are still called lcd0 and lcd1
module in the manual too.

Interestingly there is only a tcon0 module clock in the manual and no
tcon1, but that is not part of this patch.
