drivers: add snvs srtc support

Introduce i.MX SNVS SRTC support. The SRTC works with 32.768KHz.
The SRTC is in SNVS_LP domain. The SNVS_LP is a data storage
subsystem with enhanced security capabilities. Its purpose is to store
and protect system data, regardless of the main system power state.
SNVS_LP is in the always-powered-up domain, which is a separate power
domain with its own power supply. When the chip power supply domain
loses power, SNVS_LP continues to operate normally.

Since OP-TEE does not care about calendar time, there is no need
to update calendar time, we only need to read the counter and
get out the time.

The plat_prng_add_jitter_entropy is reused from tee_time_arm_cntpct.c.

When building 32-bit optee_os, CROSS_COMPILE32 defaults to CROSS_COMPILE
if not set, and CROSS_COMPILE defaults to arm-linux-gnueabihf- if not
set.

When building 32-bit optee_test, CROSS_COMPILE32 also defaults to
CROSS_COMPILE if not set, but if CROSS_COMPILE is not set, there is no
default value, causing the native compiler to be used and generating
errors and confusion.

This patch makes the behavior and expectations consistent across both
optee_os and optee_test.

core: arm32: fix native_intr_handler()

Prior to this patch when a native interrupt was received in IRQ mode
r12 wasn't saved on the stack. There's two problems with that:
1. r12 isn't a callee preserved register, but must be preserved
in an exception handler
2. Without r12 an odd number of registers was saved breaking the
8 byte alignment of the stack pointer

This patch fixes this by also saving r12 on the stack when handling a
native interrupt in IRQ mode.

core: pager: avoid page faults with pager lock held

When a normal thread takes the pager lock there must be no page faults
while the lock is held. This is has so far been ensured by feeding the
function to the KEEP_PAGER() macro, but this will only take care of the
actual code not stack usage. This patch introduces a new pager lock
function, pager_lock_check_stack() which will make sure that the
estimated needed stack is mapped before the lock is acquired.
