From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>
The state of the shared RCGs found in the SM8250 dispcc can't reliably
be queried and hence doesn't implement the is_enabled() callback.
Mark the shared RCGs as CLK_ASSUME_ENABLED_WHEN_UNUSED, to ensure that
clk_disable_unused() will issue a disable and park the RCGs before it
turns off the parent PLLs - which will lock up these RCGs in any system
with continuous splash enabled.
