The device tree reg starts at BUS_BASE + QoS_OFFSET, but the regmap
configs in the ICC driver had values suggesting the reg started at
BUS_BASE. Shrink them down (where they haven't been already, so for
providers where QoS_OFFSET = 0) to make sure they stay within their
window.

On eMMC devices the bootloader has no business enabling UFS clocks.
That results in a platform hang and hard reboot when trying to vote
on paths including MASTER_UFS and since sync_state guarantees that
it's done at boot time, this effectively prevents such devices from
booting. Fix that.

Pointers to struct qcom_icc_node (and similar structures) are not
modified, so they can be made const for safety. The contents of struct
qcom_icc_node must stay non-const.

The driver currently uses .is_bimc_node to distinguish device type BIMC
from NOC. Define type for bus/noc devices like what downstream[1] does
to make support for more types easier.

Add a driver for the MSM8996 NoCs. This chip is similar to SDM660 where
some busses are controlled by RPM, while others directly by the AP with
writes to QoS registers.
