ARM: hwcaps: add new HWCAP defines for ARMv7-A

Modern ARMv7-A cores can optionally implement these new hardware
features:

- VFPv4:
    The latest version of the ARMv7 vector floating-point extensions,
    including hardware support for fused multiple accumulate. D16 or D32
    variants may be implemented.

- Integer divide:
    The SDIV and UDIV instructions provide signed and unsigned integer
    division in hardware. When implemented, these instructions may be
    available in either both Thumb and ARM, or Thumb only.

This patch adds new HWCAP defines to describe these new features. The
integer divide capabilities are split into two bits for ARM and Thumb
respectively. Whilst HWCAP_IDIVA should never be set if HWCAP_IDIVT is
clear, separating the bits makes it easier to interpret from userspace.

ARM: move memory layout sanity checking before meminfo initialization

Ensure that the meminfo array is sanity checked before we pass the
memory to memblock.  This helps to ensure that memblock and meminfo
agree on the dimensions of memory, especially when more memory is
passed than the kernel can deal with.

ARM: pm: arrange for cpu_proc_init() to be called on resume

cpu_proc_init() does processor specific initialization, which we do
at boot time.  We have been omitting to do this on resume, which
causes some of this initialization to be skipped.  We've also been
skipping this on SMP initialization too.

Ensure that cpu_proc_init() is always called appropriately by
moving it into cpu_init(), and move cpu_init() to a more appropriate
point in the boot initialization.
