[U-Boot] [U-Boot, v5, 01/18] arm: boot0 hook: move boot0 hook before '_start'

[Philipp Tomsich]

> The boot0 hook on ARM does not insert its payload before the vector
> table. This is both a mismatch with thec comment above it and
> contradict usage of the boot0 hook on ARM64.
> 
> To fix this (and unify the semantics for ARM and ARM64), we change the
> boot0-hook semantics on ARM to match those on ARM64:
>   (1) if a boot0-hook is present it is inserted at the start of
>       the image
>   (2) if a boot0-hook is present, emitting the ARM vector table
>       (and the _start) symbol are suppressed in vectors.S and
>       the boot0-hook has full control over where and when it
>       wants to emit these

Applied to u-boot-rockchip/next, thanks!
