Subject: [PATCH 4.17 06/66] clk: aspeed: Mark bclk (PCIe) and dclk (VGA) as critical

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Joel Stanley <joel@....id.au>

commit 974c7c6d7ba5a4b12d99456b0599aa6326dc2b69 upstream.

This is used by the host to talk to the BMC's PCIe slave device. The BMC
is not involved, but the clock needs to be enabled so the host can use
the device.
