Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

Now that the GIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static.

In preparation of moving gic code to drivers/irqchip, remove the direct
platform dependencies on gic_raise_softirq. Move the setup of
smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask
function to trigger wake-up IPIs.

The socfpga_boot_secondary is correctly marked as __cpuinit but references
secondary_trampoline, which was introduced into the init section, causing
this build warning:
WARNING: vmlinux.o(.cpuinit.text+0xf90): Section mismatch in reference from the function socfpga_boot_secondary() to the variable .init.text:secondary_trampoline
The function __cpuinit socfpga_boot_secondary() references
a variable __init secondary_trampoline.
If secondary_trampoline is only used by socfpga_boot_secondary then
annotate secondary_trampoline with a matching annotation.
The solution is to mark secondary_trampoline as cpuinit as well.

Early printk code needs UART to be mapped early during
boot. early_printk() is left there during the start-up; it is useful
as our emulators are fairly slow.

Building a multiplatform kernel with combined armv7 and armv6
kernel does not work with the socfpga smp code, which contains
v7-only instructions. Since this code never runs on armv6,
we can annotate the assmebly with .arch armv7-a, as suggested
by Russell King.

This lets us build a multiplatform kernel for experimental purposes.
However, it will not be useful for any real work, because it relies
on a number of useful things to be disabled for now:
* SMP support must be turned off because of conflicting symbols.
Marc Zyngier has proposed a solution by adding a new SOC
operations structure to hold indirect function pointers
for these, but that work is currently stalled
* We turn on SPARSE_IRQ unconditionally, which is not supported
on most platforms. Each of them is currently in a different
state, but most are being worked on.
* A common clock framework is in place since v3.4 but not yet
being used. Work on this is on its way.
* DEBUG_LL for early debugging is currently disabled.
* THUMB2_KERNEL does not work with allyesconfig because the
kernel gets too big
[Rob Herring]: Rebased to not be dependent on the mass mach header rename.
As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
picoxcell, mvebu, and socfpga are converted.
