Now that imx_pinctrl_probe accepts const struct imx_pinctrl_soc_info
we can constify all declarations of struct imx_pinctrl_soc_info.

For some SoCs the struct imx_pinctrl_soc_info is passed through
of_device_id.data which is const. Most variables are already const
or otherwise not written. However, some fields are modified at
runtime. Move those fields to the dynamically allocated struct
imx_pinctrl.

Various IMX platforms may have different imx_pmx_ops.gpio_set_direction
implementations, so let's make it platform specific callbacks instead of
the fixed common one.

Currently only VF610 platform implements it. No function level changes.

MX7ULP MUX mode mask and shift bit is different from VF610.
Let's make it a platform specific property for the later easy of
adding MX7ULP support.

One trick in exist code that Vybrid hardcoded the config part
as 0xffff because its mux_config register BIT[15-0] are all configs
part. But it's not true in ULP, so use mux_mask instead to address
the difference.

The Kconfig currently controlling compilation of this code is:

drivers/pinctrl/freescale/Kconfig:config PINCTRL_VF610
drivers/pinctrl/freescale/Kconfig:	bool "Freescale Vybrid VF610 pinctrl driver"

...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.

Since module_init wasn't in use by this driver, the init ordering
remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

To support i.MX7D Low Power State Retention IOMUXC, commit e7b37a52
("pinctrl: freescale: imx: allow mux_reg offset zero") changes the way
of zero mux_reg offset support with a new flag ZERO_OFFSET_VALID.  But,
unfortunately, it forgot to add this flag for vf610 pinctrl which has
zero mux_reg offset be valid as well, and hence breaks the vf610
support.

Fix the regression by adding flag ZERO_OFFSET_VALID for vf610 pinctrl
driver.

A platform_driver does not need to set an owner, it will be populated by the
driver core.
Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

The pinctrl driver initialized the register offsets for the pins
with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl
mux register. So far, this was solved using the ZERO_OFFSET_VALID
flag which allowed offsets of 0. However, this does not allow to
verify whether a pins struct imx_pmx_func was initialized or not.

Use signed offset values for register offsets and initialize those
with -1 in order to detect uninitialized offset values reliable.
