This commit fixes the FPSCR register initialisation validation test for the ARMv8.1-M architecture. For ARMv8.1-M, the newly added LTPSIZE field in the FPSCR may always read the value of 4 when the M-Profile Vector Extension (MVE) is not implemented or FP context is not active, so we must ignore its value when validating the FPSCR register initialisation.

This commit updates the `arm_no_multithreading` test to run on the recently added `mps3_an547` board. The `mps3_an547` SoC includes the Cortex-M55 processor which implements the ARMv8.1-M architecture that is not covered by any of the boards in the current "allowed platforms" list for this test.
