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

sunxi: DRAM initialisation for sun9i
This adds DRAM initialisation code for sun9i, which calculates the
appropriate timings based on timing information for the supplied
DDR3 bin and the clock speeds used.
With this DRAM setup, we have verified DDR3 clocks of up to 792MHz
(i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.
