[PATCH v2 0/4] u-boot: add SCMI GPIO/Pinctrl support

[Dan Carpenter <dan.carpenter@linaro.org>]

There is an existing SCMI pinctrl driver in drivers/pinctrl/nxp/ which
lets you configure the initial state of the pins via device tree.  This
patchset is a more generic version which provides GPIO as well.

I wrote two small cleanup patches to the NXP driver, one which renamed
an enum and another which made some white space changes.

The next patch adds an pinctrl driver which lets you configure the
initial state for the pins.  But the main thing is that we need one
driver to handle the SCMI pinctrl protocol so the pinctrl driver does
this.

The last patch adds GPIO support over SCMI.

I tested this code using the SCP SCMI server on OP-TEE over Qemu.  I
created a custom mock pinctrl device in SCP.

Changes since v1:
Address Peng Fang's review comments.
Use the standard gpio-ranges to describe the pins instead of
inventing a custom format.
