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.

capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver

rockchip: video: Kconfig: set MAX_XRES and MAX_YRES via Kconfig
This introduces two new Kconfig options that configure the maximum
allowable framebuffer size (i.e. the memory reservation/allocation for
the framebuffer):
- VIDEO_ROCKCHIP_MAX_XRES
- VIDEO_ROCKCHIP_MAX_YRES
The resulting memory allocation will cover 4 byte per pixel for these
resolutions.
