Make these const as they are only used during a copy operation.
Some structures are used as a copy operation inside __init functions, so
make them const and replace __initdata with __initconst to avoid section
conflict error.

This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers. Intel and Realtek have been especially active here.
- Continued work towards moving everything to the component model from
Morimoto-san.
- Use of devres for jack detection GPIOs, eliminating some potential
resource leaks.
- Jack detection support for Qualcomm MSM8916.
- Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson

gic_set_affinity() manually copies the provided cpumask to the struct
irq_common_data affinity field, returning IRQ_SET_MASK_OK_NOCOPY in
order to prevent the core code from doing that.
We can instead simply let the core code do it for us, by returning
IRQ_SET_MASK_OK instead of IRQ_SET_MASK_OK_NOCOPY & doing the copy
ourselves.

Currently in gic_set_affinity() we calculate a temporary cpumask holding
the intersection of the provided cpumask & the CPUs that are online,
then we call cpumask_first twice on it to find the first such CPU. Since
we don't need the temporary cpumask for anything else & we only care
about the first CPU that's both online & in the provided cpumask, we can
instead use cpumask_first_and to find that CPU & drop the temporary
mask.

When parsing mti,reserved-cpu-vectors we generate a mask of all bits
that have been declared reserved, the loop through starting from bit 2
to find one that isn't reserved (ie. is zero).
This patch accomplishes the same task more simply by:
- Inititialising the reserved mask to 0x3 (ie. the 2 software
interrupts). This means we don't need to skip them later as the loop
previously has.
- Replacing the loop checking for zero bits with find_first_zero_bit,
which fits our needs now that the 2 software interrupts are marked
reserved. This requires that the type of reserved is changed to
unsigned long so that it's suitable for use with bitmap functions.
- Replacing the magic number 8 with the hamming weight of the ST0_IM
field - ie. the number of bits that a MIPS CPU has for interrupt
inputs. This is still a compile-time constant 8, but makes it
clearer why it's 8.

This patch avoids the need to read the GIC_SH_MASK* registers when
decoding shared interrupts by setting & clearing the interrupt's bit in
the appropriate CPU's pcpu_masks entry when masking or unmasking the
interrupt.
This effectively means that whilst an interrupt is masked we clear its
bit in all pcpu_masks, which causes gic_handle_shared_int() to ignore it
on all CPUs without needing to check GIC_SH_MASK*.
In essence, we add a little overhead to masking or unmasking interrupts
but in return reduce the overhead of the far more common task of
decoding interrupts.

- Moving the decision about whether to use gic_cpu_pin or timer_cpu_pin
outside of the loop.
- Using the new write_gic_vo_map() accessor function to avoid the need
to handle each map register separately.

Simplify the reads of the bitmaps indicating pending & masked interrupts
in gic_handle_shared_int() using the __ioread32_copy() &
__ioread64_copy() helper functions.

We currently have __ioread32_copy, __iowrite32_copy & __iowrite64_copy
helpers in lib/iomap_copy.c. This patch adds __ioread64_copy to round
out the set, allowing copies from I/O memory using 32 or 64 bit reads.
[ralf@linux-mips.org: Changed to move all the code of this patch to be
applied to arch/mips temporarily.]
