Updates:
dt-bindings: reset: eswin: Documentation for eic7700 SoC
v3 -> v4:
1. Remove register offsets in dt-bindings.
2. Changed the const value of "#reset-cells" from 2 to 1.
Because the offsets were removed from dt-bindings. There are
only IDs. And removed the description of it.
3. Modify copyright year from 2024 to 2025.
4. Redefined the IDs in the dt-bindings and used these to build a
reset array in reset driver. Ensure that the reset register and
reset value corresponding to the IDs are correct.

v2 -> v3:
1. Drop syscon and simple-mfd from yaml and code, because these are
not necessary.
2. Update description to introduce reset controller.
3. Add reset control indices for dt-bindings.
4. Keep the register offsets in dt-bindings.

v1 -> v2:
1. Clear warnings/errors for using "make dt_binding_check".
2. Update example, change parent node from sys-crg to reset-controller
for reset yaml.
3. Drop the child node and add '#reset-cells' to the parent node.
4. Drop the description, because sys-crg block is changed to reset-
controller.
5. Change hex numbers to decimal numbers going from 0, and drop the
not needed hardware numbers.

reset: eswin: Add eic7700 reset driver
v3 -> v4:
1. Add 'const' for the definition. It is 'const struct of_phandle_
args *reset_spec = data;'.
2. Modify copyright year from 2024 to 2025.
3. Included "eswin,eic7700-reset.h" in reset driver.
4. Added mapping table for reset IDs.
5. Removed of_xlate and idr functions as we are using IDs from DTS.
6. Removed .remove function.

v2 -> v3:
1. Change syscon_node_to_regmap() to MMIO regmap functions, because
dropped syscon.
2. Add BIT() in function eswin_reset_set() to shift the reset
control indices.
3. Remove forced type conversions from function eswin_reset_of_
xlate_lookup_id().

v1 -> v2:
1. Modify the code according to the suggestions.
2. Use eswin_reset_assert() and eswin_reset_deassert in function
eswin_reset_reset().
3. Place RESET_EIC7700 in Kconfig and Makefile in order.
4. Use dev_err_probe() in probe function.
