drivers: pinctrl: add pinctrl support

Add support for pinctrl support using device-tree. The device-tree
"pinctrl-<x>" and "pinctrl-names" properties are supported and
allows to apply a pinctrl configuration based on this. This support
also includes a way to register pin muxing controllers that can apply
these states.
A few properties of the pinctrl nodes are supported such as
"bias-disable", "bias-pull-up" and "bias-pull-down".

drivers: scmi-msg: add support for clock using generic clock framework

Integrating the clock framework with SCMI allows to avoid boilerplate
code to do so in platform specific files. This patch adds a generic
layer that uses the generic clock framework to access and expose clocks.
SCMI clocks can be added from platform code using scmi_clk_add().
A new CFG_SCMI_MSG_USE_CLK configuration option is added to enable
this generic clock support.

core: ffa: parse boot info

With CFG_CORE_SEL2_SPMC=y OP-TEE is executed as an SP at S-EL1. The
manifest describing the OP-TEE SP is passed as a boot argument.

The manifest contains among other things the two properties
"load-address" and "mem-size". These cover the secure memory allocated
for OP-TEE to cover core and TA memory. The retrieved memory range is
saved with a call to core_mmu_set_secure_memory() to be used when
initializing MMU and other memory configuration.
