arm64: zynqmp: Define routines for mmio write and read
Define routines of mmio write and read functionalities
for zynqmp platform.
Also do not call SMC from SPL because SPL is running before ATF in EL3
that's why SMCs can't be called because there is nothing to call.
zynqmp_mmio*() are doing direct read/write accesses and this patch does
the same. PMUFW is up and running at this time and there is a way to talk
to pmufw via IPI but there is no reason to implement IPI stuff in SPL if
we need just simple read for getting clock driver to work.
Also make invoke_smc as global so that it can be reused in
multile places where ever possible.

arm64: zynqmp: spl: fix dual SD controller support
When enabling both SDHCI controllers, spl_mmc.c would actually choose
device sdhci0 even if booted from sdhci1 (boot_device). This is because
spl_mmc_get_device_index(boot_device) expects BOOT_DEVICE_MMC2[_2] in
order to return index 1 instead of 0.
The #if defined(...) statement is copied from board/xilinx/zynqmp/zynqmp.c

ARM: fixed relocation using proper alignment
Using u-boot-2017.05 on i.MX6UL we ran into following problem:
Initially U-Boot could be started normally.
If we added one random command in configuration, the newly generated
image hung at startup (last output was DRAM: 256 MiB).
We tracked this down to a data abort within relocation (relocated_code).
relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop
iteration until the source pointer is equal to __image_copy_end.
In a good case __image_copy_end was aligned to 8 bytes, so the loop
stopped as suggested, but in an errornous case __image_copy_end was
not aligned to 8 bytes, so the loop ran out of bounds and caused a
data abort exception.
This patches solves the issue by aligning __image_copy_end to 8 byte
using the linker script related to arm.
I don't know if it's the correct way to solve this, so some review would
be very appreciated.
