Arvind M 8942623b15 gpu: host1x-nvhost: avoid setting flcn irq at boot ...

[1] The DLA firmware configures the DEST and MASK registers during
    the initialization.
[2] In OOT, the DLA KMD is accidentally setting the interrupts. This
    will result in enabling additional interrupts that the firmware
    does not handle (like NVDLA_GENERIC_INTR_FAULT_CRITICAL).
[3] This commit fixes the issue by avoiding the interrupt settings
    at the DLA KMD.
