core: introduce STPMIC1 driver

STPMIC1 is a power management chip for the stm32mp1 platform. It is
accessed through an I2C bus. STPMIC1 provides regulators and other
features as interrupt sources and watchdogs.

STPMIC1 configuration is expected from a secure device tree blob, that
currently is the embedded DTB.

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.

core: user_ta: support mapping paged parameters

Supports mapping shared paged parameters for user TA.

vm_map() is modified to map objects with the TEE_MATTR_EPHEMERAL
attribute which is an indication that it's a parameter instead of TA
code/data or permanent mapping.

tee_mmu_clean_param() is added to clean out all parameters added with
tee_mmu_map_param().

In tee_mmu_map_param() instead of clearing out any old parameters
there's a check to see that there's no old parameters hanging around.

Finally mobj_update_mapping() is removed since the pager now supports
shared mappings.

core: pager: record fobj in pmem instead of area

Records the fobj backing the physical page represented by a pmem instead
of struct tee_pager_area which was used prior to this patch. Each fobj
can be used by several unrelated areas in the end allowing real shared
memory between multiple user context.

Reference counting for the page tables is increasing in activity since
entries which are hidden/unhidden also decrease/increase the count. This
is because there's no difference between unhiding a pmem or just mapping
it again in another page table.

The memory sharing is not fully taken advantage of in this patch.
