    xen/arm32: Introduce alternative runtime patching
    
    This patch is based on the implementation of ARM64, it introduces
    alternative runtime patching to ARM32. This allows to patch assembly
    instruction at runtime to either fix hardware bugs or optimize for
    certain hardware features on ARM32 platform.
    
    Xen hypervisor is using ARM execution state only on ARM32 platform,
    Thumb is not used. So, the Thumb only branch instructions (CBZ, CBNZ,
    TBB and TBH) are not considered in alternatives.
    
    The left ARM32 branch instructions are BX, BLX, BL and B. The
    instruction BX is taking a register in parameter, so we don't need to
    rewrite it. The instructions BLX, BL and B are using the similar
    encoding for the offset and will avoid specific case when extracting
    and updating the offset.
    
    In this patch, we include alternative.h header file to livepatch.c
    directly for ARM32 compilation issues. When the alternative patching
    config is enabled, the livepatch.c will use the alternative functions.
    In this case, we should include the alternative header file to this
    file. But for ARM64, it does not include this header file directly.
    It includes this header file indirectly through:
    sched.h->domain.h->page.h->alternative.h.
    But, unfortunately, the page.h of ARM32 doesn't include alternative.h,
    and we don't have the reason to include it to ARM32 page.h now. So we
    have to include the alternative.h directly in livepatch.c.
