This mc_ch_readl(MC_GLOBAL_INTSTATUS) is replicated by every
tegraxxx_mc_get_channel(), it should be a part of common interrupt
handler, IMO.
And then I'd rename that callback to global_intstatus_to_channel().

dev_err_ratelimited("unknown interrupt channel 0x%08x\n", status) and
should be moved to the common interrupt handler.
