Use unified assembler syntax (UAL) in assembly files. Divided
syntax is considered deprecated. This will also allow to build
the kernel using LLVM's integrated assembler.

Now that we have migrated all users of the legacy private SA1111 gpio
interfaces, we can remove these redundant GPIO interfaces.

This patch adds support for the Broadcom Brahma-B15 CPU readahead cache
controller. This cache controller sits between the L2 and the memory bus
and its purpose is to provide a friendler burst size towards the DDR
interface than the native cache line size.

The readahead cache is mostly transparent, except for
flush_kern_cache_all, which is precisely what we are overriding here.

The readahead cache only intercepts reads, and does invalidate on
writes (IOW), as such, some data can remain stale in any of its buffers, such
that we need to flush it, which is an operation that needs to happen in
a particular order:

- disable the readahead cache
- flush it
- call the appropriate cache-v7.S function
- re-enable

This patch tries to minimize the impact to the cache-v7.S file by only
providing a stub in case CONFIG_CACHE_B15_RAC is enabled (default for
ARCH_BRCMSTB since it is the current user).

Map the interrupt numbers for SA1111 through the SA1111 IRQ domain
rather than doing our own translation.  This allows us to eliminate
the irq_base sachip member.

SA1111_VBASE, SA1111_p2v, SA1111_v2p, _SA1111, SA1111_ADDR_WIDTH,
SA1111_ADDR_MASK, and SA1111_DMA_ADDR are not used anywhere in the
kernel, so remove these redundant definitions.

Remove the special sa1111 mmio accessors from core sa1111 code, and
their definition in sa1111.h now that all users are gone.

The legacy device-driver suspend/resume methods are not used by any of
our drivers, so let's remove this redundant code.

Since the only user of the SA1111 device driver shutdown method has now
gone, we can kill the bus level support code and the entry in the
sa1111 device driver structure.
