Ioannis Glaropoulos 03734eeb1e arch: arm: protect r0 in z_arch_switch_to_main_thread() inline ASM
Adding r0 to the clobber list in the inline ASM block of
z_arch_switch_to_main_thread(). This instructs assembler
to not use r0 to store ASM expression operands, e.g. in
the subsequent instruction, msr PSR %1.

We also do a minor optimization with the clearing of R1
before jumping to main.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.

Getting Started
***************

Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview,
and the documentation's `Getting Started Guide`_ to start developing.

Community Support
*****************

Community support is provided via mailing lists and Slack; see the Resources
below for details.

Resources
