armv8: add hooks for all cache-wide operations
SoC-specific logic may be required for all forms of cache-wide
operations; invalidate and flush of both dcache and icache (note that
only 3 of the 4 possible combinations make sense, since the icache never
contains dirty lines). This patch adds an optional hook for all
implemented cache-wide operations, and renames the one existing hook to
better represent exactly which operation it is implementing. A dummy
no-op implementation of each hook is provided.

ARM: tegra: translate __asm_flush_l3_cache to assembly
When performing a cache disable function, code must not access DRAM.
That is because when the cache is disabled, it will be bypassed and all
loads and stores will be serviced by RAM. This prevents accessing any
dirty data in the cache. In turn, this means the stack cannot be
used, since that is in RAM. To guarantee that code doesn't use RAM (and
in particular the stack) __asm_flush_l3_cache() must be manually
implemented in assembly, rather than implemented in C since the compiler
won't know not to touch RAM.

mx6sabresd: Make Ethernet functional again
Since commit ce412b79e7255770 ("drivers: net: phy: atheros: add separate
config for AR8031") ethernet does not work on mx6sabresd.
This commit correctly assigns ar8031_config() as the configuration
function for AR8031 in the same way as done in the Linux kernel.
However, on mx6sabresd design we need some additional configuration,
such as enabling the 125 MHz AR8031 output that needs to be done
in the board file.
This also aligns with the same method that the kernel performs
the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

armv8: define get_ticks() for the ARMv8 Generic Timer
For 64-bit ARM systems we provide just a timer_read_counter()
implementation and rely on the generic non-uclass get_ticks() function
in lib/time.c to call the former.
However this function is actually not 64-bit safe, as it assumes a
"long" to be 32-bit. Beside the fact that the resulting uint64_t
isn't bigger than "long" on 64-bit architectures and thus combining two
counters makes no sense, we get all kind of weird results when we try
to OR in the high value shifted by _32_ bits.
So let's avoid that function at all and provide a straight forward
get_ticks() implementation for ARMv8, which also is in line with ARMv7.
This fixes occasional immediate time-out expiration issues I see on the
Pine64 board. The root cause of this needs to be investigated, but this
fix looks like the right thing anyway.
