Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

Core changes:
- Augment pinctrl_generic_add_group() and pinmux_generic_add_function()
to return the selector for the added group/function to the caller
and augment (hopefully) all drivers to handle this.
New subdrivers:
- Qualcomm PM8998 and PM8005 are supported in the SPMI pin

- Intel Ice Lake PCH (platform controller hub) support.
- NXP (ex Freescale) i.MX8MQ support.
- Berlin AS370 support.
Improvements to drivers:
- Support interrupts on the Ocelot pin controller.
- Add SPI pins to the Uniphier driver.
- Define a GPIO compatible per SoC in the Tegra driver.
- Push Tegra initialization down in the initlevels.
- Support external wakeup interrupts on the Exynos.
- Add generic clocks pins to the meson driver.
- Add USB and HSCIF pins for some Renesas PFC chips.
- Suspend/resume support in the armada-37xx.
- Interrupt support for the Actions Semiconductor S900 also

- Correct the pin ordering in Cedarfork.
- Debugfs output for INTF in the mcp23s08 driver
- Avoid divisions in context save/restore in pinctrl-single.
