media: camss: Add SM8250 bandwdith configuration support

Downstream makes some pretty explicit comments about voting for bus
bandwidth prior to camcc_camnoc_axi_clk_src. Working with camx downstream
also shows that the bandwidth vote is required to get that root clock
working.

Add a simple mechanism to declare set and unset named NOCs. Whereas the
objective is to enable the sm8250 specifically the code has been
implemented to allow setting of whatever NOCs different SoCs using this
driver may require.
