dt-bindings: mfd: dual licensing for st,stpmic1 bindings

Change include/dt-bindings/mfd/st,stpmic1.h license model from GPLv2.0
only to dual GPLv2.0 or BSD-2-Clause. This change clarifies that
this DT binding header file can be shared with software components as
bootloaders and OSes that are not published under GPLv2 terms as
OP-TEE OS is.

This change has been discussed and acked in the LKML [1].

stm32mp1: update DTS files to Linux kernel 5.2-rc1

Synchronize stm32mp1 DTS files with those published in Linux kernel
source tree at commit a188339ca5a3 ("Linux 5.2-rc1").

This change updates platforms EV1 and ED1 and introduces DK1 and DK2
known as DiscoveryKit board. It also introduces stpmic1 bindings header
file needed for platform DTS files compilation.

Among other changes, this commit introduces STPMIC1 and BSEC description
nodes. STPMIC1 defines regulators. BSEC describes fuses and uses the
status / secure-status to define fuse access scope in the scope of BSEC
support.

This change strictly dumps Linux kernel DTS files into OP-TEE but
regarding stm32mp157c.dtsi for which the OP-TEE DTS file adds node
for the ETZPC device which is mandated by OP-TEE but not defined in
non-secure Linux kernel scope.
