STIMER is can only access in secure mode if the SoCs supports trust,

The commit message does not really tell what the source changes are
(although it seems to describe part of the motivation for this change).

We don't have support for the PX30 in the U-Boot code base yet.
Until a series to add support for the PX30 comes in, you should not have
this here yet (and then add this specific case when the PX30 support is
added).

This should not be in Kconfig and rather in a header-file.
With what you do here, a user (e.g. via 'make menuconfig') or a defconfig
file (e.g. due to a typo) could accidentially change overwrite this.
