[PATCH v3 2/4] clk: bcm: rpi: Mark PIXEL_CLK and HEVC_CLK as CLK_IGNORE_UNUSED

[Maíra Canal]

If PIXEL_CLK or HEVC_CLK is disabled during boot, the firmware will skip
HSM initialization, which would result in a bus lockup. However, those
clocks are consumed by drivers (vc4 and HEVC decoder drivers,
respectively), which means that they can be enabled/disabled by the
drivers.

Mark those clocks as CLK_IGNORE_UNUSED to allow them to be disabled by
drivers when appropriate.
