clk: qcom: gcc-sdm855: Add the HALT_DELAY flag for some GCC clocks

The multimedia AHB clocks off of GCC are needed for any accesses
on the multimedia clock domains. These multimedia AHB and XO
clocks, barring the graphics and NPU ones, need the MMCX rail to
be enabled prior to turning on.
Since there is no way for the clock driver to take care of this
dependency during probe when it tries to enable these clocks, add
the BRANCH_HALT_DELAY flag to them. This avoids any of the warnings
which are inevitable due to the clocks not turning on.
Since the parent dependency on the MMCX rail is listed for the MM
GDSCs, an enable vote would be made on it prior to turning on the
GDSC, which would then lead to these clocks turning on.
