6df4393daf clk: oxnas: Add OX820 Gate clocks
Add support for the Oxford Semiconductor OX820 SoC gate clocks
along the OX810SE SoC support.
This rework on concerns the gate clocks since they are different.
Future PLL handling code will be added for OX820.

5a9e54a81b clk: oxnas: Refactor to make use of devm_clk_hw_register()
Make usage of static tables identified by the OF match table to
feed devm_clk_hw_register() and use of_clk_add_hw_provider().

This structure is cleaner and simplifies adding new SoC support while
having common probe and gate ops code.

80c6397c37 clk: oxnas: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/clk/Kconfig:config COMMON_CLK_OXNAS
drivers/clk/Kconfig:    bool "Clock driver for the OXNAS SoC Family"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

a5e9b85a65 clk: Fix return value check in oxnas_stdclk_probe()
In case of error, the function syscon_node_to_regmap() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().
