When compiling the kernel in thumb2 (CONFIG_THUMB2_KERNEL option activated), we
hit a compilation error. The error message is listed below:
---8< -----
Error: cannot use register index with PC-relative addressing -- `str r0,.saved_lpr'
--->8----
Add the .arm directive in the assembly files related to power management.
