kernel/sim-armv7: Fix os_arch_frame_init symbol type
Without symbol type GNU ld does not properly detect call to ARM code
from Thumb code and does not generate proper instruction to switch
modes which results in a crash.
.p2align 4, 0x90 /* align on 16-byte boundary and fill with NOPs */
.globl os_arch_frame_init
+ .type os_arch_frame_init, %function
/*
* void os_arch_frame_init(struct stack_frame *sf)
*/
