  metag: checksum.h: fix carry in csum_tcpudp_nofold

In csum_tcpudp_nofold, add 1 if the carry bit is set after adding the
destination IP address (32 bits) to the checksum (16 bits).

The lack of carry handling for this particular addition meant that a
destination address of *.*.255.255 (e.g. certain broadcasts) sometimes
resulted in an incorrect checksum. This bug has been present in the Meta
port since the code was written in the 2.4 days.

Pull Metag architecture changes from James Hogan:
 - Infrastructure and DT files for TZ1090 SoC (pin control drivers
   already merged via pinctrl tree).
 - Panic on boot instead of just warning if cache aliasing possible.
 - Various SMP/hotplug fixes.
 - Various other randconfig/sparse fixes.

 "The major change in this pile is ->readdir() replacement with
  ->iterate(), dealing with ->f_pos races in ->readdir() instances for
  good.

  There's a lot more, but I'd prefer to split the pull request into
  several stages and this is the first obvious cutoff point."

Commit 106c992a5ebe ("mm/hugetlb: add more arch-defined huge_pte
functions") added an include of <asm-generic/hugetlb.h> to each
architecture's <asm/hugetlb.h> (except s390).  Unfortunately metag was
missed which resulted in build errors when hugetlbfs is enabled (see
below).

Add the include for metag too to fix the build errors:

  mm/hugetlb.c In function 'make_huge_pte':
  mm/hugetlb.c +2250 : error: implicit declaration of function 'huge_pte_mkwrite'
  mm/hugetlb.c +2250 : error: implicit declaration of function 'huge_pte_mkdirty'

If the common clock framework is enabled, call of_clk_init(NULL) in
time_init() to register device tree clocks with the clock framework.

After this time_init() calls a new function init_metag_clocks(), which
looks for a clock named "core" in the node compatible with "img,meta"
(usually the root node). If found the get_core_freq machine callback is
overridden to obtain the core clock frequency using that clock.
