gpu: host1x: API to load streamid registers

Browse Source 
Define host1x_dev_ops for T186

Add API load_streamid_regs() to load streamid registers
Set this API to host1x_dev_ops.load_regs so that we
set streamid registers during host1x_probe()

Add a static table which includes streamid mappings
for all the clients
