ad892d310e irqchip/eznps: Fix build error for !ARC700 builds
[ Upstream commit 89d29997f103d08264b0685796b420d911658b96 ]

eznps driver is supposed to be platform independent however it ends up
including stuff from inside arch/arc headers leading to rand config
build errors.

The quick hack to fix this (proper fix is too much chrun for non active
user-base) is to add following to nps platform agnostic header.
 - copy AUX_IENABLE from arch/arc header
 - move CTOP_AUX_IACK from arch/arc/plat-eznps/*/**

fcc80f8ed9 arc: [plat-eznps] fix data type errors in platform headers
[ Upstream commit b1f32ce1c3d2c11959b7e6a2c58dc5197c581966 ]

Add <linux/types.h> to fix build errors.
Both ctop.h and <soc/nps/common.h> use u32 types and cause many
errors.

Examples:
../include/soc/nps/common.h:71:4: error: unknown type name 'u32'
    u32 __reserved:20, cluster:4, core:4, thread:4;
../include/soc/nps/common.h:76:3: error: unknown type name 'u32'
   u32 value;
../include/soc/nps/common.h:124:4: error: unknown type name 'u32'
    u32 base:8, cl_x:4, cl_y:4,
../include/soc/nps/common.h:127:3: error: unknown type name 'u32'
   u32 value;

../arch/arc/plat-eznps/include/plat/ctop.h:83:4: error: unknown type name 'u32'
    u32 gen:1, gdis:1, clk_gate_dis:1, asb:1,
../arch/arc/plat-eznps/include/plat/ctop.h:86:3: error: unknown type name 'u32'
   u32 value;
../arch/arc/plat-eznps/include/plat/ctop.h:93:4: error: unknown type name 'u32'
    u32 csa:22, dmsid:6, __reserved:3, cs:1;
../arch/arc/plat-eznps/include/plat/ctop.h:95:3: error: unknown type name 'u32'
   u32 value;

66619433d0 ARC: [plat-eznps] remove IPI clear from SMP operations
Today we register to plat_smp_ops.clear() method which actually
is acking the IPI.
However this is already taking care by our irqchip driver specifically
by the irq_chip.irq_eoi() method.
This is perfect timing where it should be done and no special handling
is needed at plat_smp_ops.clear().

86c25466f7 ARC: [plat-eznps] Use dedicated identity auxiliary register.
With generic "identity" num of CPUs is limited to 256 (8 bit).
We use our alternative AUX register GLOBAL_ID (12 bit).
Now we can support up to 4096 CPUs.
