arm: arm64 32bit address relocation

Current relocation code is limited to 21bit PC-relative addressing
which might not be enough for bigger code sizes. The following patch
increases the addressing to 32bit PC-relative. This feature is
specially interesting if U-Boot is build without optimiation (-O0) as
the text section is increased significativelly.
