Commit r312747 ("Setup decoding windows for ARMADA38X") resulted
in build failing for Marvell platforms, which don't have AHCI controller.
This patch provides a fix by adding dummy functions for such cases.
On the occasion rename register dump routine to decode_win_ahci_dump,
in order to avoid confusion.

- Replace pcpu_find(curcpu) with get_pcpu(), which is much
more direct.
- Remove armv4 pcpu fields which I added in r286296 but never
needed to use.
- armv6 pc_qmap_addr was leftover from the old armv6 pmap
implementation. Rename it and put it to use in the new one.

Change sysmap initialization to only allocate KVA pages for CPUs that

While here, collapse CMAP3 into CMAP2 (their use was mutually exclusive
anyway) and "recover" some space in PCPU padding that has always been
available due to 64-byte cacheline padding.

- Pad the packet using m_append(9), if the packet has enough space for
padding, which is usually true, it will not be necessary append a newly
allocated mbuf to the chain.

engine and 3D requires not yet started nouveau driver.
These drivers forms a first non-x86 DRM2 enabled graphic stack.
Note, there are 2 outstanding issues:
- The code uses gross hack in order to be comply with
OBJT_MGTDEVICE pager. (See tegra_bo_init_pager() in tegra_bo.c)
- Due to improper(probably) refcounting in drm_gem_mmap_single()
(in drm_gem.c), the gem objects are never released.
I hope that I will be able to address both issues in finite time,
but I don't want to touch x86 world now.

In case where GICD_CTLR.DS is 1, the IGROUPR registers are RW in
non-secure state and has to be initialized to 1 for the
corresponding interrupts to be delivered as Group 1 interrupts.
Update gic_v3_dist_init() and gic_v3_redist_init() to initialize
GICD_IGROUPRn and GICR_IGROUPRn respectively to address this. The
registers can be set unconditionally since the writes are ignored
in non-secure state when GICD_CTLR.DS is 0.
