arch/armv7-r: Fix armclang build warning: L6306W

Browse Source 
When a function is known to preserve eight-byte alignment of the stack, armclang assigns the build
attribute Tag_ABI_align_preserved to that function. However, the armclang integrated assembler does
not automatically assign this attribute to assembly code.
